When I was about 17 I developed a rash that started on my elbows and spread down my arms to my wrists and also on my knees and feet (mainly my toes) it was very itchy. I went to a dermatologist who didn't know what it was and gave me a steroid cream. The cream did not help. The rash eventually went away on it's own. Since then the rash has reocurred, not as severely though. Every few months I will get a few spots on my fingers or just on my knees. The rash seems to appear during or around my menstrual cycle. The rash has returned this time with a vengance, it is on both of my legs from hip to ankle and on my arms from elbow to wrist. This rash itches horribly. I've taken benadryl wich helped with the itching but the rash did not go away. I have been using over the counter anti-itch creams to get by. I don't want to spend the money for a doctor visit if they just tell me they don't know what it is. Can someone help identify this please. Your help is appreciated.
