Last July (02) I went to dermatologist for itchy rash on arms, legs, breasts. He ruled out scabies, ringworm, gave me Zyrtec & betamethoasone valerate lotion. It did go away finally. Now this July about 3 wks ago, it started again on my arm, sides and one breast. I thought it wierd but then it got very severe on my neck, face with red areas, some pimply itchy bumps, some fat bumps but major itching. And I got severe anal itching with no bumps. I literally could scratch my skin off, it is so bad.I never had it on the face before and was recently exposed to hot weather area. I bathe in Aveeno, take the Zyrtec, got a kenelog shot from the hospital 3 days ago. The betamethasone does not stop the itching. I called 2 drs and they just say well, rashes are hard...am I doing all that can be done? I am very afraid of facial scarring but this itches like crazy, and why in July? Could this be a nerve reaction, allergy or heat rash? I have not changed any products and have lived in the same geographical area for years. Husband has nothing. Please help.
