Yes, your chance for permanent scaring would increase, but I think it is up to the individual...I rotated fina on my traps and delts with no probs...A little discomfort was all..
Cheese is bad for any diet...
Also some FYI, the dye that is in yellow cheese is very bad for the stomach...My freind used to get sick from it, he now uses white cheddar...So I now use it also...
Pork is the worst meat for you...Tricanosis(sp?) And other parasites live in most pork products (non-processed)...
Stick with Red Meat, Fish , Chicken...
