Hi, Welcome to Health care magic forum.
As you describe it is an
allergic reaction to some thing,it may be the food,clothes,wool,cosmetics, or soap. Try to avoid these one by one and try to find the allergen.
Inverter may not have any relation to the
allergy, but should not be kept,in a closed room, some or other ventilation should be allowed.
I advise you to consult a chest physician for diagnosis and treatment.
I usually prescribe to my patient with such symptoms cifiime,phenylelphrine hydrochloride,levocitrizine,ammonium chloride.
Avoid taking fruits, juices, ice water, ice cream, and the things allergic to you.
Wishing for a quick and complete recovery. Thank you.
