I googled it as well and found the same thing. It seems to be pretty common.
I figured I'd post in case somebody else had similar issues and it turned out to be the gear. I actually have a buddy who get big ass knots on his back and shoulders when he uses Cyp. Guess I'll just keep an eye on it and see what happens. If it doesnt subside, I'll go to the doc.
Thanks for the reply bro.
