Considering your chief compain might require root canal treatment .

Although it is not possible to give a rational opinion without look at the clinical condition of the tooth and the X-ray of the tooth, the only tentative suggestion that can be given based on your description of the symptoms, you will require root canal treatment for permanent relief of your symptoms. But still, the most prudent step would be to visit a dentist and get yourself evaluated clinically so that the right treatment options can be explained to you. Regards.
