Cold sores

Question:

dear sir;

WHY WOULD A COLD SORE GO AWAY THEN COME BACK, GO AWAY COME BACK ETC ETC ETC????

Answer:

That is what they do.  The virus that causes them lives safely inside a nerve ganglion in your head and comes out periodically, causing a cold sore when you get a cold or when other triggering events (fever, trauma, sunlight, allergy) occur.
