I have a rash that starts out as sometimes 1 small flesh colored bump that itches like crazy and within hours there is several and then over days turns into a huge rash that itches like crazy, I have it on my forearms, elbows, inner wrist, palm of hand, lower back, lower stomach, behind my knee. I have had this for over 6 months now and cannot get rid of it and now my wife has symptoms and nobody knows what it is, any ideas?
