Just remember, there is no "one solution fits all" to shoulder pain. There are various different conditions that can affect the shoulder and each may vary in treatment and management.
I was walking in a parking lot in 2015. I was run over by an SUV. Had rotator cuff tears in both shoulders. But when they found that, they found that I had other problems, chronic problems.
Please be cautious regarding physical therapy. There are extremely talented physical therapists. And there are also kids, just out of school, he really do not know what they are doing. Also, there are physical therapists who just treat their work like a job. They don't care, they don't have any real devotion to the work. And they can be a problem if that is who you get.
The best are physical therapists who have a very long history of working with professional sports teams. If you get one of those, you will be in good hands.
Folks can also try going to a sports medicine doctor, instead of a regular orthopedist. The sports medicine guys just treat far, far, far, far more injuries in their practice and they are just generally, more highly skilled than any old orthopedist.
I get chiropractic and acupuncture. Both help.
I also do stretches from Hatha Yoga. That helps.
I also learned deep muscular relaxation techniques from Feldenkrais and Alexander Technique.
I had no choice. I was bedridden for two years. I was doing stretching and other therapies up to 8 hours a day, until I figured out how to conquer a lot of my problems.
Whatever health care professional you use, I would ask them for stretches that you can do daily to help.
I would also ask if there are sleeping positions that better support and help the shoulder.
If you sleep in a bad position at night, you are basically doing "anti-healing" for 8 hours straight. That is a length of time that creates a force, hard to oppose. It can go to positioning work with pillows.
I use a special pillow and a special mattress.
Also, with shoulders...be very very very careful about exposing your shoulder to cold in winter and causing the muscles to seize up. Keep very well bundled up in winter.
Ask the doctor what weight limit your shoulder can handle. Some folks do all kinds of healing work...and then carry a 50 pound sack of mulch to the backyard...and ruin all the hard work.
best of luck folks...
