I have rash on both hip areas and knees with dots now throughout my lower legs and some on my wrists, family md did biopsy, came back as pleva. derm wants to do more biopsies-I don t want more biopsies, have had since November and now is at its worse. have tried oral and topical steroid, no changes. sitting under a grow-light light takes some of the redness away? not sure what to try, tried burdock, didn t do anything. doesn t seem to be diet related, blood-work came back neg for gluten issue.
