How can i treat a cold sore inside my lip as fast as possible?

Otc meds: Cold sores are caused by the herpes simplex virus. Over the counter medications can bring relief but not cure - the virus lasts 4-8 days.

Time: If it is inside your lip chances are it is an apthous ulce r not a viral cold sore. Nothing but time is needed. Usually 7-10 days. But otc kanka swabbed on the lesion will sooth and coat and decrease pain!
