Surgery is required for a tear.
If it's tendinitis you may be able to work it out with rest and pain relievers. It's your body telling you to stretch and strengthen your shoulders. Don't neglect it or you will end up under the knife. I did and it's not fun. Turned into a 6 month healing process, and a full year before full recovery.

I agree with Barry. I had rotator cuff surgery on my left shoulder in January 2024. No club swings until almost June. Still working on regaining swing speed. Mine issue was from a car accident and had a complete tear.

I wouldn't mess with the tendonitis. Are you doing PT? or just anti inflamatories?? I'd ask the PT for some stretches and exercises to work on strengthening the shoulder. Also, you might want to check with your pro as to the cause of the tendonitis. If it's swing related, it will just return once you start swinging again.

If not a tear you should be able to rehab without surgery. If you can find a sports medicine doctor to take a look and give you an evaluation. For tendonitis a lot of times rest is the first step before any PT.

Most patients don’t require surgery. Usually you can knock it back with a steroid shot and a course of therapy. Important to strengthen the shoulder and shoulder blade muscles. Therapy will help train the smaller muscles you usually wouldn’t target in the gym. Titleist has a team of therapists who have undergone some specific training as it relates to golf. I believe it’s called the Titleist Performance Institute or TPI. See if you can google a therapist in your area who has undergone that training. Also I know physical therapists can become board certified sports physical therapists. The American Board of Sports Physical Therapists should have a list of qualified therapists. You can go on their website and look. I’d also look for a certified hand therapist if you can. Don’t let the name fool you. They’re occupational or physical therapists that specialize in the entire upper extremity who have undergone rigorous training and are considered subject matter experts in their field.

i hve seen one here in my area. i’m in Chicago and it’s right by one of the el stops which makes it nice, i just have to remember which stop and what line it is lol.

I feel your pain, I dislocated my shoulder about 9 years ago then tore my rotator cuff the following year.
I had an operation on it about 7 years ago now, I’ve spent countless visits to physio, couple of injections, heat treatments, acupuncture etc. I still get pain in it.
They are talking about another operation.
No matter what you do, please take your time getting back into golf.
They keep telling me I went back to golf too soon and that’s what caused it worse.
Good luck and speedy recovery! ️‍♂️
