Thanks for the query.
You might be suffering from urticaria
It is a chronic condition and shows a poor response to treatment.
Antihistamines are the only treatment available.
Dont take steroids
they may harm you, instead you can use antihistamine daily.
Please meet a dermatologist
if it persists.
Let me know if you have any other doubt.
