I've had erythema multiforme for 20 months now. Doctors not being very helpful. Likely not herpes simplex. What should I do?

I've had erythema multiforme for 20 months now. Doctors not being very helpful. Likely not herpes simplex. What should I do?

Still maybe herpes: As you seem to know, erythema multiforme can be triggered by recurrent HSV infections. But "likely not" is pretty vague. If there is no other explanation, ask your doctor about anti-HSV treatment (e.g. valacyclovir) to see if it helps. The drug is harmless, so why not try? You also should have an HSV blood test, even though such testing is (wrongly) deemphasized in Canada. See a dermatolgist. ...Read more

Will my Erythema Multiforme flare up if I get a tattoo?

Probably not: The reports are flares or local EM-like reactions to henna and to some of the bright colors. Ordinary black tattoo ink is less likely to be a problem.
