Hmm, so you want to figure out if you tore your pec. You have 1 of 2 options:
1) Ask getbiggers, because all getbiggers are experts on medicine.
OR
2) Go see an actual medical doctor.
This is a tough call. Getbig is filled with experts related to a variety of disciplines, including physics, biology, psychology, history, economics, politics, chemistry, medicine, sociology, etc.
