Ive had this problem for over 2 years. I was initially diagnosed with viral meningitis and this post viral fatigue but instinct said somthing different as I never had a fever etc. Initially started with an unbelievable headache. Then I developed a really heavy sensation along the back of the head and heavy sensation in nose and jaw. As a child I used to pop my jaw the whole time. Mt teeth dont meet and I cant open my jaw fully. On numerous times Ive had the sensation that I couldnt open my jaw and this whole thing began when my teeth began to involuntary chatter. When the sensation in my head is really strong if i press down on my scalp or face or even shoulders but particlarly the bease of skull then the sensation eases. The ringing in my ears over 2 years is getting worse and the nausea after 2 years comes in waves. [also when I had root canal treatment over 6/7 years ago the pain I developed in my face afterwards couldnt be explained by the dentist even though he had to keep taking breaks - he never said there was a problem with my jaw but I dont hink he thought it was relevant}Ive seen an ENT surgeon who after 5 mins said nothing wrong and a neurosurgeon who said some type of neuralgia and presecibed medication that just didnt work. After 2 years of this heavy sensationa and nausea I would really appreicate if it these symptoms could sound like TMJ to someone!
