Reoccuring sinus infection- every 3 months I have intense pain on the left side of my face and ear I'm ready for surgery antibiotics aren't enough?

Left face ear pain. 1-sinusitis can be a cause of headache at times 2-recurrent sinusitis could occur if there blockage of drainage-- 3-intolerable facial, ear pain from sinusitis should at least give you continous purulent drainage 4-it could be you have trigeminal neuralgia , which have nothing to do with sinusitis.
