Good general advice but to say that "This is caused by ..." is merely a guess. I still say that any pain that is becoming chronic needs to be looked at on an individual basis by an expert who can hopefully get to the correct diagnosis.
For example, I have maintained a thorough routing of exercise for all my life and have still fallen foul of bad posture through classical guitar playing and too much computer use.
My view is that musicians ARE athletes and that far too many do not perform any kind of musical fitness routines until such time as a problem occurs. In my case I can now relate my chronic pain to bad classical guitar posture:
Sat with foot on stool
Tense shoulders and hands
Head in forward carriage
Some musicians have clearly worked out how to sit correctly and attend very carefully to posture and playing positions but I have not done so and therefore have to deal with the consequences.
By the way - Jack Sanders has some nice videos on youtube (Guitar Salon) and looking at him play pretty much showcases what relaxation looks like.
