I don't know if anyone else has experienced this...
I used to be able to tolerate an awful lot. As a truck and car mechanic, it would get a lot of bruises, cuts, punctures, muscle strains, etc. and just kept on going. Since the RSD - and as it has progressed - it seems that many minor issues get amplified.
I have a minor shoulder injury from a fall in 2001 that is not going away. I also was just diagnosed with Rheumtiod Arthritis and the pain in my index fingers kills me at times. And so on...
While I can't totally blame the RSD for all of the aches, it does seem that I am now less tolerant, whereas I used to be more immune to pain.
"Junk", you could be experiencing something like this as well. Ada suggested sciatia, and where other folks would simply do a morning stretch and move on, it stays with you.
Just my totally non-medical observation....
Hope you can get a handle on this.
