I first was diagnosed with TOS on the right side and recently had surgery. For months before the surgery I could barely use my right arm so I forced to use my left. A month before surgery I started getting very familiar symptoms. My surgeon and PT said it's not surprising. When you're in pain you tend to sit wrong and compensate in weird ways. Also, you use the better arm more. ALso what I was told was...your anatomy is the same on both sides so "if it happened to the one side, it's pretty safe to say that it might happen to the other side"

Well now I have it on both sides and I don't know what to do. I can't use either arm well. I can't raise eithe rarm above shoulder level. It's very frustrating! You are not alone! I just wish I knew what could be done to stop this progression
