I may know feeling what you're talking about. Would you consider it also a "tingle" or an itch in your joints that is always there, but is somewhat relieved when your mind isn't on it?
The feeling also plagues and bothers me, but it hasn't been too bad lately dut to my not focusing my thoughts on it.
I get the feeling most in my left big toe joint, but it may spread to my other toes, fingers, knees, and hip/leg joints when I think too closely about it.
Unfortunately that doesn't work for me. Eventually my joints force the matter on me. Especially when I'm trying to sleep. If I'm any future indication for you, I'm quite sorry. I already mentioned how far it's spread. Sometimes it's even so deep along my spinal column that I simply can't do anything for it. It's uncrackable. I still half expect to cause some severe damage to myself just from the way I'm forced to violently crack my neck.
