Right... I had a cold sore on my lip a few months ago. It left a cut along my lip which hasn't healed for the past 3 months and if I open my mouth too wide it will start too bleed. What do I do? Its ruining my slightly dashing (not so) good looks.

It's time to see your doctor about this. A wound that hasn't healed in 3 months, and still bleeds, is something that should be looked at.

There's really no advice anyone on the internet can offer.

Please see your doctor.
