dermatitis
"I had a very itchy rash on the outside of both lower legs, also what at first was an itchy red spot became quite large on the back of my calf.  My doctor prescribed a cortisone cream that didn't help. Tried some other creams but no improvement. My legs were a mess for 12 months.
Then I saw another doctor who prescribed Elocon which I used for 3 weeks and the rash cleared up. That was 3 months ago. I am 75 years old. I will use it again if I need too."
