My MCAS is going into remission.

Hi everyone.

If you’ve happened upon this blog looking for info, you may have noticed that I stopped updating it.

That’s because I committed whole-heartedly to a program called the Dynamic Neural Retraining System.

I learned about it a mast cell support group, from someone who’d been really sick with MCAS for five years.  Like, way worse than I ever got– she couldn’t even leave her house without wearing a mask, because of how often she went into anaphylaxis.

She used the Dynamic Neural Retraining System, which is a neuroplasticity–based, mind-body program, to rewire her brain.  And it gave her her life back.

As soon as I heard her talking about it, I was so intrigued.  If you’ve read my other blogs, you’ll know that I’m a huge believer in how the nervous system can play such a key role in determining our experience of things like chronic pain.

Once I realized there was a strong relationship between the nervous system and the immune system, it was like a little light-bulb went on over my head.

So I purchased the program last fall and committed to doing it for an hour a day, every day, for a minimum of 6 months.

It’s August now, and I’m doing so much better.   The vast majority of my mast cell symptoms I had are gone, and the remaining symptoms are improving every day.

DNRS works by taking your brain out of a chronic state of fight-or-flight, and rewiring it to build the neural networks associated with rest, digest, and healing.

And it’s absolutely incredible how this can really turn people’s lives around.

It is still hard for me to talk, in detail, about everything I’ve been through, although I do plan to share more about my mast cell journey in the future.

For now, I strongly recommend you check out the following blogs to see stories of people who’ve used DNRS to recover from mast cell activation (along with other conditions).

These are some of the stories that really gave me hope, when I was struggling to believe that this could ever get better:

Another great blog is Jana Smith’s– she didn’t have mast cell, but she had a lot of weird food allergies and other things going on with her immune system:

You can also learn more by watching the DNRS testimonials on Youtube.

Is the context of when you eat and how you’re feeling, just as important as WHAT you’re eating?

This may be something that’s very individual, but for me…

I have noticed there can be a big difference in how my body responds eating the exact same foods, under different scenarios.

I’ve noticed that if I eat at times when I’m stressed out, or during transition times during the day (like let’s say I’ve been rushing around, stressed, running late for things, dealing with traffic, and then I finally get home).

I am much more likely to get weird bumps on my arms after eating in the second context, not so much the first.

I first discovered this a few weeks ago when I tried beef for the first time.  My dad made me some plain, straightforward ground beef in a pan.  He didn’t even use oil– he cooked it in its own grease.

But I happened to try it at the exact same time that my Mom gave me some really upsetting news about a family member.

Lo and behold, I got really upset, my arm got really itchy, and next thing I knew, it had a few wheals on it.

I thought it was beef that was the problem, and was scared to try it again.  However, I’ve since tried beef a few more times (both in the form of a sandwich at Panera, and also more plain cooked beef at home from Trader Joe’s) and I never got a wheal again.  Which leads me to believe it had more to do with emotional stress.

Last night I came home, again, feeling pretty late, stressed out, and in somewhat of a bad mood.  I was rushing to get my workout (of walking for 15 minutes) done before it was too late at night, and quickly just ate one piece of chicken after that.

Just one piece of Trader Joe’s frozen chicken breast, pan-fried in olive oil.  Which has been one of my safe foods…

Which is why I was SO upset when part of my arm started itching and it looked like I was getting one or two itchy bumps again.

I was really freaked out thinking I might not be able to eat chicken again, but then I thought about what Dr. Bayuk told me at my last appointment.  Which was that the bumps were not about a specific food, but a physiological response to eating.

I’m not entirely sure I agree with this, but since luckily neither he, Dr. Castels, nor Dr. Rashid think the arm bumps sound dangerous, I decided to do an experiment.

Rather than completely freaking out and assuming I can’t eat chicken anymore, I tried to calm myself down.  I read my new DNRS book for a while and watched a few of the recommended videos on neuroplasticity, which made me feel more optimistic about fixing this.  Then I actually fell asleep for a short nap.

When I woke up an hour later, I tried another piece of chicken, and it didn’t really seem like anything too significant happened.  Plus it’s hard to say what could have been a delayed reaction after my body freaked out at the first.

But what definitely did NOT happen was me getting one new, specific, itchy bump.

So, this is something I definitely need to keep in mind.  It’s something Savannah Marcum talks about in her video on MCAS recovery, about how she realized there’s no point in trying something new if she’s stressed out, because the stress itself would totally cloud her actual response to that thing.

It also definitely underscores what Dr. Bayuk said, about it being a physiological response to eating.

So… I’ll be keeping an eye on this, if it seems like I start reacting to my safe foods.  I do think my bad reaction to sweet potato when I tried it may have more to do with that specific food– but, again, I was scared when I tried it, so who really knows.

This whole experience with chicken has really impressed upon me just how integrally linked the nervous system and the immune system are.  Eating the exact same food an hour apart, when I was stressed versus not stressed, seemed to yield entirely different results.

Which is not to say that anyone should expect to totally eliminate ALL stress from their lives.  That’s not possible at all.

But it does give me up hope that, if I’m very careful to pay attention to how I’m feeling, and the relationship between the nervous and the immune system, this may lead to some more clues for healing.

After all, as Dr. Bayuk says, the two are “totally wrapped up in each other.”  The more I learn about it, the more I don’t really think you can separate the two.

(And also thinking back to Jeff’s story over at MEchanical Basis, and how he believes that MCAS is somehow neurological).

I think that makes a lot of sense.

Heyo it’s Mayo– MCAS Series #4- 20 Steps to Healing

Finding this video made a world of difference to me.  I found it at a point when I wasn’t sure if anyone ever really got better from MCAS.

Thank you so much, Savannah, for posting this and sharing your journey.

I wanted to jot down a few notes about what she said because writing is, personally, how I process and internalize things.  So I wanted to write this out, in list form, to really make sure I absorb it.

#1. Build the A-Team.  

I’ve been doing this slowly, but it’s been falling into place.

#2. Make a custom and unique health plan that works for you!

Savannah found that she was not “the average case” because she was having just about ALL of the adverse reactions.  Once she and her team decided to treat her like a 100% unique case, things got a lot better.

#3. Trust yourself 

#4. Genetic testing

I’m planning to ask her where they did this, and what kind of testing they did.

#5. Anti-histamine Medication

I’m not sure if this is going to work for me, because all ant-histamines seem to knock me out.

#6. Low-histamine and low-inflammation food

She cooks all of her food– cooking reduces histamine (?)

She explains it does cook off some of the vitamins, but it’s been working for her.

Local and homegrown produce reduces allergens as well because it’s from the area where you are.

#7. Less is more

Rather than taking multiple supplements, better to eat nutrient-rich food.

She was only able to eat 2 foods at one point.  Added in new foods very slowly.

Identified vitamin deficiencies through testing and added in very pure supplements

Only takes Vitamin C and D

#8. Small and frequent meals

Easier to digest, releases less histamine at one time

was eating a small meal hourly when she was at her worst

bumped it up to every 2 hours

#9. What you put on your body matters just as much.

Body absorbs 70% of what you put on it

switched to all-natural brands

#10 Tweak lifestyle– No stress zone

She realized it was counter-productive to add new things into her life when she was stressed.   Because stress releases histamine.  So if she was stressed, she couldn’t accurately judge if she was reacting to the new thing or not.

#11. Routine

Eat at the same times, schedule appointments at same time, same day

#12. Low stress, low inflammation hobbies

#13. Slow and steady wins the race

#14. MCAS is like PTSD of the body

Like PTSD, have to face triggers in small and controlled doses.

Have to retrain mind and body not to overreact

She and her team plan out her next steps MONTHS in advance so that, by the time comes, she is mentally prepared.

#15. Less is more

Less stress, less chaos, less pills, less ingredients  –> less inflammation, more healing

#16. Good vibes only

Life is no-negativity zone… people places even items of clothes

#17. It is “in your head”

Mindset is everything.  Have to get your mind in the right place.

“I found that training my brain to be and think healthy translated immediately to my bod being more healthy.”

“Everything is connected, so don’t neglect anything.”

#18. Mind, body, soul

Have to heal on every level.  She had to focus on it every single day.

Find something you’re passionate about– fulfill life purpose

Keeps soul aligned and feeling good.

What you put in your body matters, what you put on your body matters, where you take your body matters

#19. Listen to your intuition

Every health decision starts and ends with you

#20. There is no magic instant cure

It is a long process and it was ALL of the steps she took that saved her life.


Thank you SO much Savannah!




MEchanical Basis/Jeff’s Story

This is an absolutely amazing story from a man who became increasingly debilitated over the course of years, following infection with a viral illness.

Jeff went to hell and back, getting progressively more ill over the years.  He had Myalgic Encephalomyelitis (ME), POTS, MCAS, dysautonomia, as well as a host of other symptoms.

Jeff tells his story on his site, MEchanical Basis.

Eventually he discovered that the original virus had damaged the connective tissue in his neck, causing compression of his brain stem through a condition known as Craniocervical instability with atlantoaxial instability (CCI/AAI).

Ultimately, Jeff is the one who had to do the research and go to battle for himself (I’ll let you read his story in his own words).   It is pretty incredible, and heartbreaking what he had to go through just to be taken seriously.

What I’m also taking away from Jeff’s story is that, once he had the surgery to correct this condition and his autonomic nervous system was able to function normally again (in terms of regulating his heart rate, blood pressure, etc)., his mast cell activation syndrome WENT AWAY!

This is incredibly inspiring for me to hear, as I suspect that it was an insult to my own nervous system (in the form of a severe emotional trauma) that started me on this path, and I sometimes wonder if healing from the trauma could make it go away.

It’s certainly not a direct parallel to Jeff’s story, but what I do take away from his story is that, yes, there is absolutely a link between the nervous system and the immune system, and that if something’s wrong with the nervous system, it can throw the immune system off as well.  (And, that by treating the nervous system injury, you can also bring the immune system back into alignment).

Here is one article that Jeff shared on his Twitter feed: it’s a scientific article entitled:

Autonomic Nervous System and Immune System Interactions.

This is SUCH an inspiring story, for so many reasons.  Thank so much, Jeff, for sharing!


Dr. Castells overview on MCAD: presentation to CSF

I wish I could actually go ahead and embed this talk, but here is the link anyway.  It’s an amazing talk Dr. Castells gave to the Chiari & Syringomyelia Foundation a few years ago.

I’d seen this super-informative talk before meeting with Dr. Castells.  However, now that I’ve had an appointment with her and am watching it again, it makes a lot more sense.

Dr. Castells is super, super busy so when you *do finally talk to her, it’s really important to have all your questions ready.

So I’m going to watch this and take extensive notes before I see her again.

Notes and Questions before my next visit:

33:16 Distinguishing between mono-clonal and non-clonal MCAS

Research from Dr. Escribano in Spain:

Urticaria, angioedema, dyspnea –> likely non-clonal

Syncope, presyncope, hypotension –> CKit Mutation –> clonal.  Would need bone marrow biopsy

If my C-Kit is negative, does that rule out a clonal disorder?

23:00 Various medications

Mentions a few things we never discussed:

Ansiolytics (anti-anxiety)

COX-2 Inhibitors for pain (like Celebrex) — she told me at my appointment it was only for mastocytosis?

Medications for subsets of patients:

aspirin for those with high prostaglandins. can be hard to use, desensitize patients to aspirin

anti-leukotrines for those with respiratory symptoms, skin symptoms, swelling of tissues, bronchospasm (like singulair).

corticosteroids only used for mastocytosis

ask her how bad it is to use benadryl often




Dr. Castells on Sodium Cromolyn (Gastrocrom)

In this talk, Dr. Castells describes how the recommended therapeutic dose is 200 mg 4 times a day.  However, the drug causes so many side effects (in the intestines is what she mentions) so they start with 100 mg once a day, and increase over the course of 8 weeks.

Once they get up to the therapeutic level, there is a “profound inhibition of mast cell activation.”

sodium cromolyn = natural “cromone” that she’s been using for 20 years

Dr. Castells’ thought on food activating mast cells

I found this question on the World Allergy Organization website, where it appears doctors can ask questions of other doctors.

Here’s a question I was wondering about, myself:

Does mast cell activation and release occur in non-atopic food intolerance? What is the evidence, for and against?

By Dr Mariana Castells

There is indirect evidence through the measurement of mast cell mediators that GI mast cells can be activated by certain foods in patient with mastocytosis and MCAS. In non mastocytosis patients there is no evidence of mast cell activation in food intolerance which has a wide definition: from lactose intolerance which does not involve mast cell activation and is the result of lactase deficiency to gluten enteropathy which is an IgG mediated immune reaction.


My thoughts:

Need to find out more about this.  What is atopic and non atopic food intolerance, and how does that relate to the strange bumps I get on my arms after eating certain foods?

And do the arm bumps relate to foods that could act more locally to trigger IBS-like symptoms in the GI tract?
