Hi,
Welcome to Healthcaremagic.com.
I had gone through your question I can understand your concern about your health.
As per your history you seems to have recurrent
herpes labialis, it is a viral infection in which there are small
blister eruption near lip, chin or one side of face, blisters are pain full associated with
fever and generalized body aches, some time.
It is a self healing conditions and heals within one or two days. If it is recurrent there may be some problem with your immune system or repeated episodes which trigger it.
You need to take healthy food with vitamin B complex supplements and also visit a doctor for further evaluation.
Hope my answer will help you and visit us back if you have any further queries.
