In late January I went to a dentist for a root canal distraction. He said that my tooth was so decayed that I need a crown lenghening to fit a crown. this dentist was not a root canal specialist . RED FLAG! should of ran out at that point. A day ater the root canal extraction I started getting hot and cold flashes on my left side of my face and then it became numb. 3 week later I can breathe through my nose properly. 4 months later I now have facial fullness and is hard to breath freely. Ive gone to an ENT, neurologist, gastrologist, cardiogist. Had chest xrays, ct scans and mris. Theh ENT said I had minor sinusitis and that should not cause the problem . I took antibioticst but no difference. When I went to the neurologist he said it was left trigemenial neuropathy caused by injections and the numbness I was feeling was anxiety.. He gave me gabapentin.To make long story short, I still feel this way and it has ruined my life. I thought it was trigmenial neuralgia but I dont feel that shooting pain. I am now anxious and pace and cry alot because I feel like im suffocating. Hoping for a miracle at this point. the neurologist thinks it will go away, but as time passes Im not sure about that. If it was nerve damage would I feel pain or not necessarily. Just need to breath better to get through but it is so hard.I have to be medicated just to be functional. I dont know anymore what it could be
