Welcome to healthcare magic.
You seem to having acute urticaria
. It is similar to hay fever
, but involvis the skin instead of your respiratory system.
There are several causes of acute urticaria like drugs, pollen, food, insect bites
, infections to name a few. In many cases, a specific cause cannot be found out.
You could take antihistamines like fexofenadine
by day and levocetrizine by night for about 2 weeks. If the rash is very severe or if it causes your eyes or lips lips to swell, you may need a short course of oral steroids.
Hope this helps you.
