Hi, im new to this site and need some answers/support.
Im 18 years old, female. Since June 2007 i have been suffering from daily headaches (top of head, forehead, temples, shooting pains) jaw ache, ear pain, eye pain, sore throat, slight numbness on side of face, chest pressure. I wake up with a forehead headache, my jaw is stiff and difficult to open, and my jaw deviates to the side when i open it wide. The headaches goes away but returns in the evening. I have been to see numerous doctors (around 10) a neurologist (who diagnosed chronic tension headaches), 2 dentists, 5 opticians, and been to the Emergency Room twice with no avail. I was given amitriptyline which i took throughout february, there wasnt much change but apparently they take 4-12 weeks to work. However i had to discontinue becuase of pregnancy which i had a termination a week ago.
However, I am back on amitriptyline (since 2 days ago) but yesterday i got a really bad headache (pressure in forehead, top of head and temples) i had a pressure feeling in both my ears which i havent had before, a really sore jaw (like a deep ache). Paracetamol doesnt seem to help. I opened my jaw earlier today and there was a really loud crack on the right side, louder than usual

I also developed a burning sensation on my tongue a week ago. So me being me i got really paranoid and went to the Emergency Room, they did some checks (pulse, listening to my lungs and heart, made me walk and checked my eyes) and said basically stop worrying and gave me Ibuprofen for the pain. The pain seems to be worse when im lying down.
Ok so i know my post is long but im really scared

i didnt get an mri or ct scan becaue the neurologist + doctors have said there is nothing that warrants the need for that. I do grind my teeth at night, and i have an uneven bite ( when i put my front teeth together, the back teeth dont touch and vice versa) and also if i close my right top and bottom teeth together , the left side doesnt close together. I have "buck teeth" which i have braces to correct. So throughout the day i position my jaw forwards so my teeth dont stick out which my ortho said would strain the jaw but i feel as though right now i have never felt this bad. I havent had the ear pressure in both ears before and i was awake all night worrying about going to sleep incase i died. I live in the UK and there is not much talk about TMJ disorders, no doctor has ever connected it to my jaw ache etc. I came across it because i tend to search every syptom on the internet. Im just wondering if anyone has had these problems with diagnosis, and if your pain differs from day to day. Right now i havent felt this ill in a while. I really just want to lay in bed all day and wait till i get better but im scared i dont
Please help
P.S. has anyone experienced on/off chest pressure with tmj? ive been reading about it and some say yes and some say no? ive had my pulse checked and ive had those sticky pads on my chest that monitor heart rate and oxygen levels in the blood and also my blood pressure checked and everything is fine. my doctor says its anxiety but i get it when im not anxious

ive heard of "referred" pain etc but im still really scared!! thanks for the help.
