Migraine Headaches & Sinus Cyst

I have had all my top teeth removed in the last year, I now have an upper denture. I have had migraine headaches for years, I always have more pain on the left side of my head and the left side of my lower skull gets real sore at the base of my neck. Since I've had my teeth pulled I now have a medium to large knot on the left side of my nose. I have been to an Ear , Nose And Throat Doctor he prescribed Augmenten antibiotics when I first started the Augmenten it made the knot smaller, so we cancelled the surgery. Now about a month later he perscribed augmenten again and this time it made the knot swell up and it became hard as a rock and I have unbelievable pain and pressure in my left eye. I would like to know if my Sinus problems could be from all the cavities that I had at one time and if since I had them taken out if it could somehow affected my sinus now, and caused the knot on my nose, the Doctor said that he does not no what it is, I had a cat Scan and I don't have any drainage or phlem. Now sometimes at night my nose stops up a little and my eyes hurt. I have quit taken the last bottle of Augmenten, I took them twice a day for three days but the pain and pressure in my nose and eye were unbelievable so I stopped. My nose is swollen and painful, my left eye hurts, lots of pain and pressure. I went to an eye doctor about 1 1/2 years ago he gave me a contact for my right eye but said my left eye was fine. Please Reply I would like to no if ther is some other antibiotic or perscription that I can take or should I have the surgery, he said during surgery if it does not drain they are going to do a biopsy.
