Thanks for your query.
If you are persistently having symptoms since last 15 days which if not responding to Allegra
, Bandy-plus & Althrocin than you should better visit skin specialist.
Your symptoms suggest that you are allergic to something in your surrounding or any food item. So it is very neccessary to find out what is causing you those allergic symptoms.Since there is no associated fever
it is unlikely viral .Apply Calamine
lotion to the skin, it is soothing & will decrease the itching & will also help to decrease the boils
