Hi all! I was wondering if any of you have gotten TOS from swimming or another repetitive-motion sport? I'm a swimmer, and I've been getting the symptoms of TOS for YEARS but I never thought anything of them (I just thought that my arms were relatively weak!)

Last week I was doing kick at practice (with a kickboard, with my arms completely extended in an overhead position i guess) when my shoulder started to hurt a bit (my physio says I have a restriction in my shoulder, possibly from glenohumeral or from TOS), then my thumb started hurting like NO OTHER, then a few minutes later my pinky, ring and middle finger went numb and the underside of my wrist/forearm went tingly. So, obviously, I stopped doing the kick and started swimming because I find that moving my shoulder around helps with the pain. Well, not only did the pain in my shoulder hurt when my arm was above shoulder-level, it almost made my cry and right above my collarbone started to cramp up. This has been happening on and off for a few years, and it always somehow starts to heal itself.

This time, though, even just moving my arm into that position hurts to the point of not being able to swim, and I can't kick since that hurts too, so pretty much my training has stopped. I went to a PT and she said that it's very likely I have TOS, i have tightness in my quadrangular space, and probably a restriction in my neck t-spine.
Just for some history, my hands go numb, tingly and cold from being raised above shoulder level for more than 20 seconds. Squats with a barbell are a no-no.

Have any of y'all experienced this or know what to do about it? It's just really depressing because my shoulder really seriously hurts, and I'm afraid of what would happen if I pushed it too hard. My PT said that pushing through the pain too much (and taking Advil before practice, which I'm not supposed to do) could lead to permanent nerve damage.

Any suggestions on exercises or pain relief? I ice and heat my shoulder as well as using Voltaren Emulgel and ibuprofen after practice, and I'm trying to make my posture better....
