It is possible that you have a nasal blockage due to a mechanical defect or deviations and that has led to off and on pain in the ear. Surgery to correct this may help you as far as the pain in ear is concerned but one has to be sure that the problem is due to the nose. This is the mainstay of the whole plan. A good diagnosis that the nose is responsible for the pain and surgery of the nose will give good results. Surgery of the nose is generally safe and done under local anaesthesia.
