Elevated serotonin levels cause flushing, tingling and burning.
So obviously blocking this reaction may help.

It might be that EM is a complex multimodal problem. I've seen that Calcium channel blockers which work for some people with this, make it worse for others, for example.

Thanks for the post...all things here are helpful for some and not others.
