I have a very close friend that is into O/C's way over his head. It has consumed him, guy has a great job and makes great $$ but he's pissed it all away. Evil stuff if you have that addictive trait.
Dude I had that same thing done to my shoulder......I thought that it sucked pretty bad....took the doctor about 20 minutes to get the needle into the joint. MRI showed no tears in the rotator cuff.....no surgery for me....woo hooo
