I'm currently being treated for TMJ again, and it causes bad jaw and neck pain, as well as migraines almost daily.
The other most painful thing I have ever experienced is an ovarian cyst rupturing. I could hardly move I was in so much pain! When I went to the doctor they gave me some anti inflammatories, and I had to go for an emergency ultrasound, and a pee test. Once I got the drugs it felt like instant relief
