I have begun to have intensifying sharp pain on the left side of my head just above the ear followed by a tingling numbness in the tender area and lef?

Get it checked out. There are a few things that could cause this type of symptom. Arteries can get inflamed, (arteritis) which would cause the pain, you could be wearing glasses or a hat too long which may cause the numbness. Either way it's probably safest to have someone check it out - especially with the intensifying pain.
