please doctors in the house help a brother here! he has this blister at his lower left lip, based on my little ideal on sickness. i thought it usually comes with fever and goes as soon as the fever is gone. but his case is different because it has been on his lip for as long i can remember seems the blister does not want to go making his life uncomfortable. plsease what drugs do he need for this blister to go.

Go to the hospital, simple. General hospitals are almost free. Please.

probably as a result of std. pls visit a hospital fast.
