Hello, Welcome and thanks for posting your query to Healthcare Magic. After reading your query it appears the possibility of Urticaria . Urticaria is a common condition caused by bursting of allergy producing cells known as mast cells . As the chemical inside them is released it produces a rash which you have mentioned. There can be multiple factors producing this condition which are included in day to day life and some times it is really difficult to find one exact cause. In your case emotional or nervous state can cause the bursting of the cells. For the betterment kindly follow the suggestions below: -Apply over the counter calamine lotion 3-4 times a day. -You can do cold water compresses to reduce the intensity of itching. -Do not scratch or rub the skin as it can lead to further aggravation. -The best measure is to take oral anti histamine like loratadine or levocetrizine under medial advise. - You can take advice for your emotional instability for which there are certain medications which can be taken. There are certain breathing exercises for betterment. Despite above measures if the problem is not getting better then it is better to consult a dermatologist for best guidance. Hope these information will help. With good health wishes Dr Sanjay Kumar Kanodia MD (Dermatology & STDs)
