What you and I need Woojr, is the warm therapy pool that I used to go to several times a week. It was heavenly.
Free swim! We did our exercises and used the pool noodles or whatever we wanted. There was a corner with jets but those actually hurt so i rarely used it. All the medication in the world did not help as much as the pool. Also, it was great because there were other people who had similar or worse issues than me (well, you know what i mean) and it was a nice group to commiserate with. We talked about our doctors 🙂 and all kinds of stuff.
I am sorry you're having more pain. The jaw problem perhaps i can shed light on? i had jaw joint replacement surgery several years ago at the Mayo Clinic in Rochester MN. I had jaw/ear pain for probably 15 years before it was finally figured out (oh it's migraines, blah blah TMJ blah blah :)) it's a long saga. Have you read War and Peace? But the surgery saved my life. I would encourage you to find out what it is and don't let anyone deter you. My dentist did not know, the neurologist was unable to open the MRI that he had ordered (yes, another story) but not at Mayo btw. I persisted. You can't stay in your chair, we need you up and around 🙂
