About 18 months ago I had an inner ear infection in my left ear, I had two lots of antibiotics and the ent specialist said I had damaged the ear canal , at the same time I had to have a filling in my top left side tooth this then developed into an infection and I had to have 2 root canals and a procedure at the hospital to try and get rid of the infection, during this time I started to develop pain in the left side of my face, head neck and left side base of my head, I am on painkillers constantly for this pain and I have undergone a course of physio, this has not worked and the physio has said he can not do anymore to help. Do u think a nerve in my gum from all the dental work could have caused this. Please advise I don t know what to do next. Thankyou.
