Hi, Welcome to Health care magic forum.
It appears that they are due to the
allergy to some thing , it may be the food,clothes, woolen,soap, or cosmetics etc.
If you can trace it out by making a list of the recently started things, you can find the thing you are allergic to , and can avoid it.
There is possibility of some infection as well so to make a trial, you can use some drugs .
i usually prescribe to my patient with such symptoms citrizine, penicillinV tablets, and some
steroid ointment for symptomatic relief.
Wishing for a quick and complete recovery. Thank you.
