[|AI|]  Hi, Welcome and thanks for posting your query to Chat Doctor. It appears from your query that you are having the problem of "Chronic urticaria". This is a specific type of hypersensitivity of skin caused by multiple innumerable causes. It is characterized by transient, evanescent rash which appears for few hours to up-to 24 hours and then subside by itself. The most problematic state is the itching and redness caused by this problem. As I discussed above, the exact cause of this problem is sometimes very difficult to find out. So the best treatment available is to reduce the tendency of redness and itching by simple antihistamine. In my clinical practice I prefer to give "loratadine" tablet by mouth up to 1- 3 times a day depending on the severity of problem. It is non-sedating antihistamine so do not interfere with the alertness of the person. You need to take the antihistamine for long term and then can slowly taper it off. It is better to consult a good dermatologist who can explain the whole situation properly and then can guide you for long term. Hope these information will help. With good health wishes" Chat Doctor.
