I have had an ankle that tightens up and after I twist it around it'll crack and feel better - this has gone on for years. Now just within the past few weeks I am having problems with getting it to crack as easily, so it has been bothering me. Some other symptoms I have noticed lately - pain in bottom of other foot - sporatic tingling/numbness in my arms (up to shoulder area) to where it is sensitive to the touch - and mainly a pain in the palm of my left hand in between thumb/first finger. Bones have also been sensitive to touch off & on on the left arm also...I know a lot of strange symptoms, but I don't really know where to start. Some back pain, but nothing that really stands out.
