Diana, having you been taking any kind of medication (other than the one for restless legs)? I experienced quite a bit of muscle and joint pain from statins. It came after I had been on them for some duration, so initially I did not put it together. Neither did the three doctors (internist, cardiologist and othopedic) that I saw for the problem. It was only after I went off of them and the pain eventually subsided that I confirmed the connection. I'm not suggesting you go off of any medication on your own, but consider the possibility, even if you have been taking something for a long time.

The tingling in the hands can also be from statins, or as has been noted a carpal tunnel problem. I've had very good success from wearing wrist braces at night (although I'm not sure if that is what they are called).
