I don't have costo and I get this. Did you by chance do something like clean all of a shower in one day with the same arm? That took me to the ER once, and the doc even thought it looked like I dislocated my shoulder. nope just fibro.
I figured that from then on I really had t ostart disciplining myself, Doing les in one day on some chores, and alternating hands/arms. That was bad. Sorry you had to go thru it. if I use one too much I'll have little particularly sore spots in my chest, and all that other stuff you mention.
Seems like from then on my deltoids started acting up more. Deltoids are the top of the arm, three muscles, front middle and back. There were chores I did that after I finished I immediately changed to a button down shirt, or I knew I wouldn't be able to raise my arm to get a shirt off later. Fibro is a weird beast.
By the way, if your RX coverage is good, I love these things called the flector patch. Otherwise voltaren gel has the same med for cheaper. The patch is best. Steady coverage for 12 hrs. Post divorce, I'm gonna see if I can get patient assistance for the patch. I was at the ER recently and got an RX and to my horror it was over 200 bucks at walmart pharmacy ($232? $282?). I didn't get them. Waah.
