A member asked:

How long should the tingling sensation last with a cold sore?

A doctor has provided 1 answer

Bad news: Typically the tingling is the first sign of a cold sore which is usually the type which is following a nerve under the surface. Here again these are the type which can recurr. Watch your acid ingestion, sun exposure and if possible keep your stress level down( easier said than done) possibly taking lysine supplements may be helpful as a preventive in the future.
