Hives: Hives come and go. The best therapy is to decrease the itch-scratch cycle by taking higher doses of non-sedating antihistamines during the daylight hours and the sedating antihistamines at nighttime to get some sleep. See you allergist if this persists. ...Read more

Viral rash: Many viruses can cause a rash in addition to other symptoms such as fever and cough. Many of these rashes are not specific or characteristic enough to identify the virus. The viral rash itself is not usually serious. But it is very important to make sure the rash is not part of a serious infection such a meningococcal infection. If you have any concerns then contact your doctor immediately. ...Read more

I have had a cut and put a plaster over it for 4 days when I took it of I had bad red bumps that itchy how to get rid of them they on my knee?

I have had a cut and put a plaster over it for 4 days when I took it of I had bad red bumps that itchy how to get rid of them they on my knee?

It sounds like: your skin had an allergic reaction to something in the plaster (bandaid?) or something you put on the cut (antibiotic ointment?). If that's the case, they will go away on their own in a few days. OTC steroid cream and oral antihistamine can help in the meantime. I suggest not treating a wound this way in the future. Best wishes. Dr. Anne ...Read more

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

Behind the knees and on the inside part of the elbow too.This skin condition is called allergic dermatitis or allergic eczema.

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. It could be heat rash, a reaction of the skin to warmth and occlusion from pressure. Some drug reactions can do that as can conditions like eczema and psoriasis. ...Read more
