My 8 months of arm pain is lessoning. Today was nearly pain free. I am amazed I really don't have all this nerve injury I was told I had. But then, 3 yrs ago I strained my SI ligaments in the gym (this was what I was told), and well, instability in the low back/hips plagued me for 2 years. I got mostly better, although sitting very carefully, only walking not running, and no yoga or weights. I now really think this SI stuff was TMS too, so I've been challenging myself- sitting on couches I would never, and resuming beginner yoga. Tonight the old pain crept back, in the low back, hip, down my leg. I got scared and thought oh no I've hurt myself again. I read Steve O's post on here about how sitting is harmless. So I called my brains bluff and said I've been pain free for a year, I'm healthy and strong and I sit on a couch and this? Plus my arms feel almost pain free and now this? I just can't believe the audacity of it all, lol. The SI pain went away after plopping back on the couch (rebelliously) for another half hour. I've been sitting on the floor for 3 years as soft surfaces triggered pain. I'm wondering if others have had an "old injury" come back as they are healing from something current? Or if anyone has been diagnosed with ligament damage and later realized it was TMS and healed?
