It sounds like your arch supports may have reached their limits. I remember being at ReHab and having the therapist suddenly deciding to check my balance (this was when I was about 70). He indicated it was pretty good (for my age). I am now 92. I am very careful in how I turn. Slowly, and carefully. I can be off balance in the blink of an eye. Something about the quick turn. I do take Pregabolin for TMJ and recently had an episode that concerned me enough to call the neurologist (I never do this). I was watching TV and suddenly realized I had been (asleep) for some time. No rememberance of being tired. Did I sleep or did I pass out? Suggestion, reduce Pregabolin, and check with Cardiolgist. I now take only one Pregabolin and no further problems. So sometimes, there just is no way to know what is causing the problem and we have to become our own Sherlock Holmes. Good Luck. Signed Dr. Watson
