Ear and Jaw pain and Numbness after Rootcanal Extraction

I had a root canal back in June. Had really bad jaw pain, facial numbness, numbness in my hands and feeet and sometimes knees felt like pins and needles. I was admitted to the hospital and they couldnt find anything wrong with me, but said I had an enxiety disorder. I just had the rootcanal tooth extracted 4 weeks ago and now have bad jaw pain and ear pain and still have numbness. The ENT said the ear pain has nothing to do with my ear it is radiating pain. Any suggestions? Tweet
