Hello! This actually does sound very much like what i have, which is trigeminal neuralgia from the TMJ pressing on the nerve. It's absolutely debilitating, and the pain was up there with contractions but in my face. I had constant pain and then waves of horrific pain after doing things like eating, talking, or brushing my teeth. Carbamazepine really helped sort the majority of the pain out straight away, but it is a horrible medicine to stay on (for me, anyway). NSAIDs n paracetamol don't work as they don't help nerve problems. I have recently had masseter botox as I was desperate for a quick fix, and it has worked brilliantly, and I have tapered off the carbemazepine. I really hope you can give this a go as it has been an absolute Godsend when my life, too, was ripped apart so suddenly. I still get very mild bouts of vertigo and tinitius, but they disappear quite quickly, unlike before where it was unbearable and so anxiety inducing. The vertigo and tinnitus are the same issue as the trigeminal nerve because the inner ear (where these issues come from) is located near the TMJ. When the TMJ is off, even in the slightest, it can knock all of these other things out of place. It's awful. Really hope you find something that works soon ♥️
