Problem with rashes, allergies on my skin...?
This sounds so bizzare to me I would see another doctor if it was me I would also go and get allergy tested. The rashes all may be from something you have eaten, something you touch,pollen, animals anything really so I would seriously get an allergy test done so that way you know what to avoid. I've had them done many a time because as a child I was allergic to over 3000 things until you know what is causing the problem don't try and put anything on the rash because you might make it worse. If it continues to get worse go the hospital and they may be able to help you out more and tell you why this is happening.
Reply:Hi, I'd definately get a second opinion from a dermatologist.
