after having 3 months of strange mouth sores, i was diagnosed with herpes simplex 1. once i'd been told what they were and how to treat them (including a valtrex perscription) the outbreak has pretty much cleared up.
except for one sore that remains. it's been there for approximately 4 weeks. it was the last to develop and also the largest and most painful. at its height, there was some yellowish puss that drained. once this happened it decreased dramatically in size but still remains. when i push my tongue against the inside of my mouth corresponding to the sore, the middle appears to be white, possibly with some fluid or something inside.
is this just a cold sore that won't go away? i've been wanting to open it and try and drain out whatever is inside but i don't want to irritate it and make it worse. could it be a bacterial infection in the skin? if so what can i do to heal it? could it be a staph infection? if so, what are my options if i don't have insurance and therefore can't get antibiotics?
