I was in mva. mri shows rotator cuff tear, labra tear and tendinitis on shoulder. emg shows pinched nerve. will physical therapy help and how long?

Can't answer w/o inf: The space here is limited to provide a good answer to your question. You should speak to an Orthopedic Surgeon or sports medicine doctor (rehab?) to answer this question. Generally, rest, ice, & compression is used to help support healing. Anti-inflammatories like Tylenol (acetaminophen) could be used also. Later on, rehab is used when healing has started but timing is up to the surgeon.
