For the past two months, I've been getting red rashes in the evenings, mostly on my face, back, and feet. They last for about 2-3 hours and then go away on their own. Allegra makes them disappear, but they come back about 48 hours later. This happened last year too around August, but Allegra worked back then. What's going on, and how can I figure out a solution?
Clinsol gel for local application is advised for 3-6 weeks.
