Apparently back pain and discomfort can go into the arms and legs. Has that happened to you?
I had some back pain once and it shot into my arms and hands, I actually went to a chiropractor and she bent me back into shape and the pain was gone.
Do you know what Chronic fatigue syndrome is? I know that the fatigue is not because of exertion or some other medical condition. It's essentially unexplained. Any idea what causes it? Ive heard of it, and of course have felt fatigue just from everyday life, but I cant say its chronic.. No, doctors still do not know the cause.  It could be biology, genetics or in someone's head from what I understand anyways. Ive been looking into pain causes, has ive always dealt with back pain, been following some research being done by some doctors that are big into treating pain with weight lifting, it really has made a difference for me. alot of what they say is pain is mostly in your head.
Discomfort can radiate into the arms and hands as well as the legs or feet, and may include numbness, or weakness in the legs and arms.
