Trying to Calm Down a MCAS Flare-up: Being Quiet and Reducing Stress

Approximately a year and a half ago I was in Accident and Emergency (the ER for US readers!) at 3am. Unknown to me at the time I was having a MCAS flare-up with significant symptoms (mast cell activation syndrome). I had woken up boiling hot, shaking like a leaf and with very painful burning skin on my face. It was truly terrifying.

This post is my story and for informational use only. It should not be taken as medical advice in any way, and it is important that you consult with a doctor if you have MCAS (or suspect you do) and follow their advice. Always consult a doctor before taking a new supplement.

The struggle for a diagnosis

At A&E, they did nothing other than take some blood and give me anti-nausea medication. I wasn't nauseous, so that prescription remains a mystery! Of course, MCAS wasn't going to be on the forefront of the minds of the doctors or nurses, as it is a rare condition. I frequently come across medical professionals that have never heard of it; some google it in front of me . . .

I was finally diagnosed with MCAS some months later, and prescribed antihistamines and mast cell stabilisers. I was also advised to take quercetin, a flavanol that is being investigated as a supplement to help the condition, and follow a low histamine diet. In my opinion, the combination of these medications, supplements and dietary changes has stopped my condition from becoming worse.

However, I do still suffer from flare-ups of symptoms. I think most people with chronic illness, whether MCAS or another condition, will agree with me when I say that a flare-up of symptoms is an emotional time.

If things have been a little better, a set-back of heightened symptoms seems so unfair. It makes progress seem futile, perhaps impossible. It makes you sad, and down. I spend ages going over and over what I have eaten, how I've exercised etc etc to try and work out what caused the flare. Sometimes I can figure it out, most times I am none the wiser.

The experience of a MCAS flare-up

Today, as I am writing this, I have just had a really nasty flare-up of MCAS symptoms. For the past few days my skin has been intensely painful due to flushing, and I am so tired despite sleeping fairly well. My joints hurt, there is itchy skin and a permanent heightened headache.

Although I don't know why my symptoms have flared, I know that any form of stress makes it far worse. So worrying over little things, as has happened a few times recently, isn't helpful.

When I feel a flare-up starting, I know I have to make some changes and be more attentive to my health and my outlook on the increased symptoms. I can't change that I have this condition, but I can change my reaction to it.

Being stressed and angry will undoubtedly happen from time to time. I think it is a natural response. But instead of sulking, I can do nice things and enjoy myself as best I can. Hopefully, reducing stress will also help with symptoms.

Personally, I find that the following are the most beneficial:

Eating a low histamine diet

I follow the SIGHI food list to eat a low histamine diet, and try to eat predominantly whole foods rather than processed ones. That's not to say that I am perfect, and sometimes I have an ill-advised treat now and again, but when I am in a flare-up I go back to basics and eat nutritious food I prepare myself, including from my own low histamine recipes.

And eating a low histamine diet doesn't have to mean boring food - have you seen all the cookies in my 'snacks' section on the low histamine recipes page?!

I also like to look at cookbooks to find something fun to eat that fits with this diet. Some helpful low histamine cookbooks (not all follow the SIGHI list):

• The 4-phase Histamine Reset Plan
• Histamine Intolerance: The Cookbook
• Mast-cell Friendly and Low Histamine Cooking

Relaxation techniques

Relaxation is pretty individual and we all like to do different things. For me, being outside, in the park or my garden, is one of the most restful things I can do. Perhaps it is cliche to say, but I find being in nature very calming. A picnic, and a good book and I am very happy for a few hours!

I also like to meditate for its calming feeling. Some good apps include Insight Timer and the Calm app. Just five minutes makes me feel more grounded.

Other ways to practice some self-care include reading for fun, watching a light-hearted movie, arts and crafts, playing with a pet, colouring books, a gentle walk (if able) or some slow stretches.

Prescribed medications

I always take my prescribed medications of mast cell stabilisers and anti-histamines, but when I am in a flare-up I am even more attentive to timing my medication correctly, and making sure I don't forget to take anything.

Supplements

There are some supplements, including quercetin, which studies suggest works as a mast cell inhibitor. I take these everyday, whether in a flare-up or not, but make doubly sure to take them when my symptoms are increased. I find quercetin to be particularly beneficial, and am thankful my doctor recommended it to me. Always consult with a doctor before taking a new supplement, as some people may not be able to tolerate.

Read relevant books

There are three books on MCAS that I return to when I am in a flare-up to sort-of 'check in' with my condition, educate myself and make sure that I am doing everything I can in terms of lifestyle changes to help myself. The three books I find very helpful are:

• Mast Cells United, by Amber Walker
• Never Bet Against Occam: Mast Cell Activation Disease and the Modern Epidemics of Chronic Illness and Medical Complexity, by Dr Lawrence Afrin
• My Crazy Life: A Humorous Guide to Understanding Mast Cell Disorders, by Daniel and Pamela Hodge

I'm not perfect, and my response to a flare-up will not always be that positive. But being aware that there are options to dealing with a flare makes me more likely to choose self-care over anger. And that can only be a good thing.

I do want to emphasise that this isn't medical advice, and if you are in a flare-up of symptoms it is always advisable to speak to your doctor for professional advice.
