Since having a blister (cold sore) up my nose it hasn't healed and bleeds often..... can you help?

See MD: You need to see your local doctor and get a prescription for acyclovir. That is the medicine to treat a herpes outbreak.

Needs attention : I would have a physician look at it. There are many reasons you could have a sore in your nose and most are benign but because its not healing you need a good plan for maintenance or observation. Maybe even a biopsy.
