I'm experiencing lots and lots of pain in my tmj at the moment. It hurts so much that taking pain killers don't do a thing. I have a question for anyone that has experienced a similar thing. Did your tmj ever cause you very bad arm pain? It started with lots of pain in my left lower arm. Now the pain is in both my arms and hands and all my fingers. My arms feel tired, like I have been lifting heavy weights. Also, if I wake up in the middle of the night, both my arms will be completely numb, sore, and covered in pins and needles. This sensation begins from slightly under my shoulders down to my fingers. Could it be my tmj? Or could it be neurological? Also, does your thoracic spine affect sensation in your arms? Because MRIs of my cervical spine and brain are clear :)
