I’ve had recurring right shoulder pain for a while, especially when and/or after sleeping on that side. After playing tennis yesterday, it flared up.
The pain is dull and localized to the outside of the shoulder, around where the upper arm meets the shoulder. I have no limitation in range of motion.
Could this be a rotator cuff issue or bursitis?
For those who’ve experienced something similar:
What helped you recover?
Which exercises or treatments worked?
How long did you stop playing tennis?
Appreciate any advice!

Is it physically and mentally possible or are those trying fooling themselves? I am not sure if I am making much progress.
