Itchy rash: Rashes are notoriously difficult to solve without seeing them. Hives are like raised patches and can be described as water-filled. Several treatment modalities would help you in that case. Contact allergy may be more likely and an Allergist can help identify triggers and treat that as well. Step 1 is to try not to rub/itch it, which makes the itch worse in either case. ...Read more

I have a bright red (and itchy!) rash on the back of both my legs, between my butt and knee. It looks like small bug bite like bumps. Not spreading.?

Many causes: Rashes are challenging even when the doctor can see them, so even harder in this forum. Small red bumps on both legs make me think of reactions to clothes, or something in contact with that area on both sides. Bites can do it.

If you have put away the new bedspread and continue to have the skin rash more than a week after, consider seeing a dermatologist. In the meanwhile, try topical hydrocortisone cream. ...Read more
