That fact that it keeps on coming back! I work on my issues, I accept the diagnosis and the symptom of the moment dies away then after a few weeks a new one comes back or the old one starts up again, the staple is the wrist pain when I use a computer (I refuse to call it RSI, because RSI does not exist only TMS exists). TMS is not like getting a vaccine, bang and the problem is gone you are protected. You have to constantly work on it because if you stop it comes back. Wish there was a way to just get rid of it for good, but at least my symptoms are fully manageable now.
