I don't always read the postings or chime in if I do, but this caught my eye (and I've tried a few things recently that seemed to have helped I want to share also)...
My mom takes ami for both cluster headaches and vulvadynia, which closely resembles neuropathic pain that is in women's genital region. Stress kicks it into high gear, as it does my EM.
My EM has improved a lot with adding a few key supplements that I read about online: Hesperidin (I have taken for mild swelling in my ankles also with success), slippery elm, and black cohosh (it used to help my menopausal hot flashes, so thought I'd try for the EM). I also take a high dose of vitamin E most days (800-1200 mg ... which bothers knowledgeable doctors since it has been known to increase risk of stroke ... I'm willing to chance it after being so miserable from EM); due to a sensitive gut, I take the "dry" form, otherwise I can't tolerate E at all.
I am among the more fortunate of those with EM -- it's stayed almost entirely on my face, ears, and chest, maybe (?) because I started looking for solutions relatively early and various testing indicates my immune system is fairly strong. I'm also among the most fortunate of those who have contracted Lyme -- I got the bull's-eye rash and knew what it meant, and began immediate, aggressive treatment (with both antibiotics and the key herbals recommended to treat Lyme ... there are great references online for these, and several helpful books). I was so successful killing off the Lyme and perhaps other tick-borne bacteria that I developed a horrendous head-2-toe yeast infection that took 6 weeks for my dr. and I to realize that it wasn't the Lyme rash!
And I've been dealing with Chronic Fatigue Syndrome (also known as CFS and CFIDS -- chronic fatigue/immune dysfunction syndrome) for a couple of decades. My immune system seems to have a delayed then overdone reaction to threats, and I rarely get sick with regular stuff such as colds or the flu. When I do, it can take 2 or 3 months for me to feel at all well again. Strangely, my EM tends to diminish when I'm dealing with this kind of "nuisance" illness, I just realized as I wrote this -- probably because I am so sick that all I can do is sleep, so I don't experience my usual, everyday stress.
As others have written, quite often, 1 or 2 regular-strength aspirin help decrease an acute EM flare. But the herbal supplements I mentioned earlier have made the biggest difference for me.
Well wishes to all who suffer with this torment ...
