Multiple reasons: There are multiple possibilities... From a cracked tooth, to infection, to a dentist missing one canal... Return to your dentist and have them take an x-ray and diagnosis the cause of the pain.

Varies: Even though the nerve in the tooth has been removed the surrounding tissues are still alive. You can still get pain from those areas if there is inflammation or infection. There is also the possibility that the tooth is fractured.
Dr. Randolph Todd
Endodontics 44 years experience
Many Possibilities: Pain can come from infection or trauma. In the case of prior root canal treatment it is possible you have a persistent infection. If the pain is immediately after the treatment it may be traumatic. I suggest you seek the care and advise of the dentist that previously treated you to determine the cause of your specific case. Good luck.

Ice: Try to limit the pain killers. Usually an absolute max is 8/day. It depends on the drug and the strength. Cold packs for 15-20 minutes at a time can help. There are many different meds to try if the 1 you are using is not effective.

Dr. Robert Kwok
Pediatrics 33 years experience
Need full evaluation: A person with hearing problems since age 5 years will have had evaluations by her pediatrician or primary care doctor, been referred to an audiologist for complete testing, and been seen by an ENT doctor to find out if there is any correctable disorder causing the hearing problems. If these things have not been done, she should write down her story and take it to her primary care doctor to start.

Cartilage: Xray doesn't show cartilage damage. If knee pain is persistent despite normal x-ray then MRI should be done to explore other possible cause.

See a doctor: This no longer sounds like influenza. If flu to begin with this can predispose you to secondary acute bacterial pneumonia which can be potentially very severe and even fatal. Please go to an emergency room asap and be examined and treated. Do not wait. Hope you are better soon.
