I get the most noticeable flushing on my cheeks and over the bridge of my nose and, of course, my ears, but I feel the burning/flushing all over. I didn't realize it was histamine related until the dermatologist showed me that I had dermatographism.
If you google or do a search for NeuroProtek here, you can find out quite a bit about it. The only side effect I'm getting from it is pain in my shins and left thigh bone. Since I'm not reacting in any other way, I'm assuming that stabilizing the mast cells in my bone marrow must be doing something positive. I'm only taking a pill or two a day. I haven't come across any masto patients taking more than a few pills a day despite the weight recommendations listed on the bottles. They say you need a trial of several months to really test it, but some have noticed benefits right away.
Camas, has nueroprotek reduced your flushing? I was doing very well on zantac but eventually my stomach stopped being able to tolerate it and now I've had terrible flushing and sickness episodes several times a day every day again. The zantac was a lifesaver but began to cause a terrible stomach ache for me. I am really unhappy about it, I was finally doing better!
