Hello doctors, kindly help me as from last 3 days I am feeling a itching and red hot spots on whole body and all this getting scary due to hot hives. Few days before I had some veg sandwich and fruit lassi. After had that in night approx 11 pm, itching with hot small red spots which was getting bigger ,got started. Then I had livocitrazin 5 mg, which place gave me a bit relief from that but last night again it started. Kindly suggest me what to do further, please suggest medicine.
