I Begin Having Severe Upper Left Jaw Pain One Week

I begin having severe upper left jaw pain one week ago. I have been talking antibiotics since that day. One round of levaquin and now amoxicillin with no relief and only worsening pain. I have no facial tenderness only jaw pain. I have no teeth where the pain is and no wisdim teeth? Went to er did cat scan. Showed an area in maxillary area that they say is sinus infection. This is hurting excruciating pain. Ive had sinus infection this is something else?
