Shingles are one form of the herpes virus and are treated with anti viral drugs. Usually the pain you feel with them is a deep pain that is probably quite different to any other pain you would normally feel. Get it checked out ASAP because the pain can become chronic, and the shingles virus near the eyes can be quite dangerous.
Good luck- I hope you get on top of whatever it is quickly.
ETA: you can get shingles even if you have had chicken pox already.
