Wow! Your story is like a mirror image of mine! I started having what I thought was dental problems approximately 1 year ago. To make a long story short I had a crown placed, a root canal done, had many dentist and endodontist appointments before they finally gave up and determined thatw my on-going and progressive pain was a medical rather than dental issue. I visited a walk-in clinic where I was diagnosed with TMJ. I was prescribed muscle relaxers, pain medicine, told to invest in a mouth guard for teeth grinding, and sent on my way. I followed the doctor's orders and found that the pain only continued to worsen. I decided to seed a 2nd opinion from my primary care doctor. He questioned the TMJ diagnosis and ordered an MRI, as the pain had radiated from my mouth/face and into my head. Following the MRI, I was referred to a neurologist who mentioned the possibility of trigeminal neuralgia. We're still not 100% sure of that diagnosis as this point, but it's looking like that will probably be what it is. I still need to have an MRA of my brain and an MRI of my lumbar spine along with an ENT specialist appointment to rule everything else out. In the mean time, I've been prescribed Tegretol and Lortab for the pain and the wait continues.
