I feel you bro!! I'm 32 and pulled my back out last Tuesday. I haven't been to the gym since. I feel like a bum Lol. I went to the dr, he gave me gave me a script for "Flector" patches. It's like a icy hot times 10. It was so bad I would cough, or sneeze I'd be in sooooo much pain. It deff does suck getting old bro. Good luck man. I've been also living on Aleve since last Tuesday.
The worst part is hurting yourself with an exercise you do all the time and then the healing taking forever. I just read radar's what's the hurry thread, and IIRC you said you were 37.
