Greetings .Hives (chronic urticaria) is a condition where an itchy rash persists on and off for six weeks or more. 'Chronic' means persisting for a long time or constantly coming back.In many cases the cause may be an autoimmune problem.Stress, infections,some food items or medicines may be a trigger in some cases.but without seeing can't say much.There is no point in giving non specific treatment without finding the exact cause.Kindly visit your doctor or you may can consult me via Clinic.
