My 16 year old daughter who has been swimming since she was 5 , was just diagnosed with "Venous TOS". At the Dr's advise she stopped swimming in Dec., her arm has not been swollen since or discolored. We are giving her an aspirin every day the pain is not too much if she doesn't use her arm. But when she plays her violin for two to three hours her arm shoulder, neck and arm hurt.(She is also in Orchestra). We saw a vascular surgeon a few weeks ago, he is recommending the removal of the 1st rib, and a ballon to open the vein. He says that she should be back to swimming in 4 to 6 weeks. He says she is at high risk for blood clots, that is why we need to consider the surgery. Has anyone who has had "Venous TOS" surgery under the arm recovered so soon, without complications? Has anyone just waited to see if "Venous TOS" would just get better without the surgery? I need to try to make a decision soon, but not sure what to do. Need advise. Thanks
