Could sinuses be causing my eye pain?

For 2 days now I have had a sore, tender pain behind my eye. Its tender when I press on the inside corner of my eye. It started out as a sore, bruise like pain on my upper eye lid. Now its mostly the inner corner and top of my eye. My eye is not red or watery, my vision is fine and theres no itching.I do suffer from sinus issues and allergies. My sinuses are always tight. No mucous, just always a tight pressure and I never breathe freely. Now today I took Sudafed and Tylenol to see if it is sinus related. It seems to be relieving some of the tenderness. I read that if Tylenol takes the pain away its not an eye infection which is what I was worried about. I do have a dr apt tomorrow. Has anyone else gone through this?
