Sarena, it sounds very much like you have fibrocystic change. If you haven't read our post on that yet, please do. And yes, fibrocystic change is "normal" - that is, many women have it, and it's not dangerous. As for your torn muscles - I'm sorry, I just don't know that much about other conditions. Please ask your doctor about it - and don't leave the office till you understand the answer, and have gotten all the information you want and need. Good luck - PJH
