Tore mine a little over two weeks ago. The first week was excruciatingly painful. The pain is a little better now, but still very limited range of motion.
Anybody here been through this? Did you opt for surgery or PT, and how long before you regained complete pain free range of motion?
Twice on the same shoulder. Actually tore it for the third time as the second surgery had the shoulder held together by threads. Doc said he wasn't optimistic. Go to the doctor and get an MRI. It is the only way to determine the extent of the injury.
Tears do not heal themselves so it depends on how bad it is.
Some can recover fully, others never. Getting your range of motion back is more important than strength. That will come back over time.
