I don't want to pretend to know much about golf injuries because I don't golf as much as most people here. A lot of that has to do with the fact that I was a pretty active triathlete and spent a year in 2018 training for Ironman Arizona so not much golf was had because I spent all my waking hours getting my body ready for that race....a far cry from a golf ready body. What I can stress is taking care of and listening to your body. At the beginning of this article it mentions rest....which we all naturally hate to hear. This is key in all aspects of sports, training, leisurely golf, whatever it may be. If something is hurting and not severely injured, most of the time it is inflammation and rest will solve that in the short term. Also, I would stress foam rolling, stretching, theragun, hyperice, whatever people use to increase blood flood and promote healing. This stuff works, take my word for it. Also stretching and being flexible will fix a TON of problems people have. If your body is stiff, muscles and tendons will be out of whack and working doubletime to do things that they shouldn't be doing....just to make up for little things that being more flexible can fix. I know everyone has there own allotted amount of free time (mostly spent golfing it sounds like) but really dedicating yourself to a good routing of stretching a few times a week (I try for nightly because my body is in shambles from triathlon), foam rolling and even better, getting into Yoga will honestly help a ton. It's not speculation, it is absolute fact that the more your body can move freely and not fight itself, the less injuries you will have (at least to the lower half). Getting this routine in will free up hip flexors, knee problems, achilles issues, maybe note elbow and others as I don't know much about those type of injuries, but for the people that rely more on lower body rotation and not so much arm pounding, this stuff will certainly help.
Sorry for the long rant here, this is just something I have really started to take super seriously the last 5 years and i have found it helps dramtically.
Now if I could just find a better golf game with the little time I have hehe
