Sometimes my skin gets really itchy for no apparent reason. At first I thought I was getting food allergy or other allergy. So I went to a skin specialist and he did the skin pricking test where my forearm skin was pricked with fifty kinds of allergens which could possibly cause allergy. The doctor was surprised to find that I was not allergic to any allergens. He couldn't figure out what was causing the allergy skin eruption. He actually gave up on treating me on this unknown itchy skin condition.
Since no one in the medical world could figure out what was causing my skin to get itchy, I would at least want something to calm the itchiness. The doctor prescribed me Cetirizine (Reactine) tablets to take daily. In spite of me taking the tablet orally, I still get the itchy skin and it turns bright red all over and spreads throughout my body. So I tried the Calamine Lotion but the liquid lotion made me feel so sleepy and weak all day. My skin is very sensitive to ointments and lotions. The lotion didn't help much either, it only helped for a few hours and the rash itchy feeling was back.
