As someone who has had shoulder issues for the last 25 years or so, including partial tendon tears, I can tell you that even if your tendon would have been damaged, the treatment would have been strange. With moderately damaged tendons, you want:

1. stop any inflammation, by taking NSAIDs for a few days

2. detect and correct any behavioral patterns that could have caused the presumed overwear of the tendon

2. start physiotherapy to strengthen those muscles that can take over the load from the damaged tendon

These are not quick fixes, because quick fixes don't exist here. Stuff like shockwave treatment, massages etc will only lessen the problems for a few hours at most, after which they will come back.
