Rash Under Arms and Inner Thighs
I have had a rash under both of my arms and on the inner part of my thighs for several months now. I had this skin rash problem checked by a dermatologist and the only diagnosis that I received back was that I likely was experiencing an allergic reaction to something. However, the allergen was not identified at the time. Therefore, I took it upon myself to try and find what could possibly be causing this allergic rash under my arms and on my inner thighs. For months I tried changing laundry soaps, using different bath products, and so on. However, this skin rash only goes away when I'm on Promethazine which is a histamine blocker. Unfortunately, the rash comes back after a couple of days.
It I was to describe the rash it is painful, red in color and very itchy. I was thinking that perhaps it might be caused by the Zoloft I was taking or maybe some another medication, or perhaps some type of food. The weird part about this is that the rash ONLY shows up under my arms and inner thighs and no where else. I cannot find a link with anything that would touch only those areas and cause this condition.
I have included a picture of the rash on my inner thigh. If anyone has any suggestions on what this could be or how to treat it, I would appreciate the help.
