I had been dx'd as having tendinitis, bilateral wrist strains, cubital tunnel {tennis elbow/golfers elbow}, DeQuervains {sp}, c spine strain & shoulder strains.

Most of those were wrong- or I went through all of those symptoms on my merry way to acquiring TOS { Thoracic Outlet Syndrome}.

Did the tears actually show up on an Xray? {I don't think they do, but it's been awhile since I researched on RSI injuries}
or did dr just call it that since nothing of an orthopedic cause showed on the xray?

just for your own health and wellness you might want to read on our TOS forum stickys - I have RSI links posted there too.
