Just wanted to say welcome. I am not the most informed member. I was diagnosed with TOS in 1999 and had surgery in 2000. Was pain free from 2001 until recently. From what I have read recently on this site, the area of the country you are in is a great place for TOS specialists. Dr's, PT, etc. Others will post soon I'm sure. One bit of advice my dr., Dr. Togut has recently given me is to keep a journal of what I do and when symptoms occur. Other's have said they will exercise or perform a task but symptoms don't result for hours later. This may be a way to figure out what you are doing to trigger pain. I find I sleep with my arm over my head. I have to restrain the arm during the night otherwise I wake up in major pain. My pain is on the right side and I am right handed. When I perform nrmal everyday tasks like dishes, laundry, etc. I use my right arm. I am trying to change to my left. Keeping a journal, or at least being aware of what you are doing to aggravate it may help alittle. Sorry, I am not a medical one. Good luck and welcome. Linda
