My co-worker had the procedure done under the muscle last July. She went from A- to C+. She had always been really into weights and cadio. Her doctor informed her to wait a minimum of 4-6 weeks after the procedure before starting back. She started back slowly to take precautions of injuring herself. She is now having to have surgury again, as one has shifted higher than the other. I have always wanted to increase my size, however after this....i am having second thoughts.......
