HoA, at the very least, get a diagnosis. I had chronic shoulder pain and acute elbow pain that I was living with and working around for longer than I want to admit. ART did wonders for my elbow, though it took a while to fully realize because of the nerve component. It also helped my shoulder, but didn’t fix the muscular imbalance I had. I had to do exercises that strengthened my external rotators and STRETCHED my internal rotators. Between the ART and the strengthening/stretching exercises I was prescribed, I am now totally pain free.
I see so many people with shoulder problems doing exercises for both internal and external rotator cuff muscles, which makes the weak muscles stronger but makes the stronger muscles stronger, too! End result being, the muscular imbalance isn’t corrected. The reason you stretch the stronger muscles is that they are typically tight, limiting ROM and/or the muscles that oppose or antagonize them.
Bottom line is, get a diagnosis first and then study and research the topic to find out what will correct the underlying problem. Seeking only pain releif means that you’ll have to live with the problem for the rest of your life.
BTW, accupuncture is great for pain relief, but will not fix a muscular imbalance. That from someone who is very much an advocate of Traditional Chinese Medicine.
Please let us know what you find out and how it goes!
