After tons of research I was happy to finally find this thread with other people's experience with TOS and decompression surgery. Therefore I thought I would add my experiences so far to help others just like this site did for me...

This whole thing started about 1 month ago when I found out I had a DVT (clot) in my right arm, after a 3hr clot busting procedure and balloon angioplastly I was diagnosed with Venous TOS/Paget Schroetter Syndrome. I saw a specialist at NYU and scheduled my 1st rib resection surgery.
I had surgery 6 days ago...June 9th

After surgery I didn't feel much of anything my shoulder/upper arm was very heavy feeling and numb. My chest also felt heavy due to my collapsed lung. I didn't have any drains just a chest tube to help re-inflate my lung. The tube was sewn right into my incision which was under my armpit. After time, I used the morphine pump for what pain I could feel to keep me comfortable. It was hard to find a comfortable spot to lay I needed to be propped up.

I didn't get much rest in the hospital due to noisy roomates (I was in a 6-bed unit at first to be monitored) and I had a few bouts of nausea/dizziness when they tried to switch me to vicodin. I stayed in the hospital (until Sun morning) a day longer than expected due to air left in lung after they removed the chest tube.

The 2hr ride home was tolerable, but the bumps were not fun! I have only been home for a few days but am doing pretty well. Minimal pain...more discomfort than anything. I have only taken a bath, and I can dress myself in anything that buttons or than I can pull up for the bottom. Nothing over my head. I have been out of the house a little bit each day, and moving around on my own pretty well.

My initial bandages were removed this morning I have a 2-3 inch scar under my armpit, my upper arm/shoulder area are still numb and very heavy feeling. It is hard for me to move my upper arm much, my range of motion isin't very good at the moment. I will be continuing with my exercises to help me with that. I was just told to do the "walking up the wall" exercise...

So for not even a week after surgery, I am feeling much better than I thought I would. I have just been taking Motrin during the day and 1 vicodin at night to help me be more comfortable. I am really thankful to be moving around without major limitations and pain.
I hope sharing my experience helps, reading others sure has helped me!
