Hello,
I have gone through your query and understand your concern.
You are suffering from Exercise induced Utricartia or Cholniergic utricaria.
This is the
allergic reaction to Physical exertion or sweat.
Exercise induced Utricaria 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 Utricaria or Cholinergic Utricaria 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
cetrizine.
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 areas 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.
