First of all, more power to you for taking viagara for your woman, some men would be too proud or shy!

Second, I had a cervical rib removal surgery for TOS 6 months ago on right side, complained of pain, swelling, numbness for 6 months following surgery with no one listening to me and then finally was diagnosed with CRPS/RSDS. I think you need to be evaluated for this condition although its hard to diagnose since its a syndrome. They can run bogus tests on you for this and can misdiagnose this syndrome as something else. So its tricky. Find a good physiatrist.

My RSDS started immediately after surgery and continued to get worse and now affects my entire right arm, and down my backside. Terribly painful.

Hope this helps.
