[|AI|]  Hello, I have gone through your query and understand your concern. You are suffering from Exercise induced Urticaria or Cholinergic urticaria. This is the allergic reaction to Physical exertion or sweat. Exercise induced Urticaria is caused by your body having an allergic response to exercise. Cholinergic urticaria is caused by sweating that results from a rise in your body temperature. Exercising in hot weather makes you more susceptible to cholinergic urticaria. Both Exercise induced Urticaria or Cholinergic Urticaria both needs attention, and you should consult Allergy and Asthma specialist now. You should stop exercising because it may aggravate the allergy and lead to life-threatening conditions like difficulty in breathing (As you already have asthma, exercise is not advisable till you consult the specialist). Both conditions well respond to Antihistamines like cetirizine. If you have cholinergic urticaria, rapid cooling in a cold shower can help relieve symptoms. If you have an allergic reaction to exercise or sweating, always take your medications as prescribed to avoid hives. You may need to avoid vigorous-intensity exercises or follow an approved exercise routine after discussion with Allergy specialist. For cholinergic urticaria and heat rash, preventing sweating is the best way to prevent hives. Exercise in an air-conditioned area and wear lightweight clothing. Avoid ointments and lotions that can block the pores and make you prone to heat rash. Hope this helps. Please write back for further queries. Wishing you good health.
