Q: The eosinophilia level in my blood is about 12%. In heat or at times when I am tense I develop rashes, small red bumps on my hands. I had undergone medical test for this 6 months and took some drugs. Until my medical test I did not get any allergies but after that I started getting some. Please tell me if I need to continue the medicines for a lifetime.

A:Parasitic infestations of the intestine or other areas can cause rashes and raised eosinophil counts in the blood. If this has been checked for with negative results then antihistamine treatment is the appropriate approach. Patients sometimes recover from this condition, which sounds like cholinergic urticaria, in time. It does not always respond to antihistamines, and may require stronger drugs.
