Why won't scab from hsv2 go away? what can i do? ben almost a year scab still there!

Leave it alone: You can leave it alone as it will not cause any complication, do not try to pick on it, eventually it will fall off.

Should have healed.: This could represent a non-resolving herpes infection that may require oral suppressive treatment., e.G Valtrex (valacyclovir) it may also represent something else, in either case it needs evaluation by a dermatologist.

Sore no healing: Skin cancers can appear as: a spot or sore that does not heal within 4 weeks a spot or sore that continues to itch, hurt, scab, crust or bleed for more than 4 weeks areas where the skin has broken down or become an ulcer, you can't think of a reason for this change, and it does not heal within 4 week see your dermatologist for a biopsy.
