I have daily headaches that last all day long. I've been treated for TMJ, migraines, eyesight, etc. I've had MRIs and CT scans, but nothing has helped. I'm afraid it may be atypical trigeminal neuralgia due to my symptoms being so close to those of TMJ. The headaches intensify when sitting but posture exercises haven't helped either. What should I do now? I'm desperate for relief at this point. I haven't been headache free for over a year.
