Anyone have muscle pain and tightness in their hand/wrist that is caused from TOS? I've had muscle type pains in my hand for a long time and pain when I bend my wrist back. Three hand surgeons haven't been able to find a cause. Its not related to carpal tunnel (I had that and had surgery for it, surgery was a success). The pain when I bend my wrist has only come on in the past year. MRI is negative. Any thoughts?
