Reddit mentions of Discovering the Body's Wisdom: A Comprehensive Guide to More than Fifty Mind-Body Practices That Can Relieve Pain, Reduce Stress, and Foster Health, Spiritual Growth, and Inner Peace

These problems have to do with accumulated muscular tension which over time becomes "permanent". It can be removed but it will not go away on its own. Muscles will start to stick together and more and more movement patterns are impaired. In the body, everything is connected to everything, so it is more useful to work on realigning the body as a whole.

As you have found, most regular doctors know nothing about such things and have no interest in learning.

You must now embark on a Healing Journey. You can take a self-help approach or you can spend a lot of money paying various
therapists to help you. Or you can do both. The types of therapists that may be helpful will be various kinds of "bodyworkers" - massage therapists, myofascial therapists, Rolfers, Hellerworkers, etc. Maybe some chiropractors. You might look into yoga and other types of stretching. You need to spend time checking into various approaches and helpers to see what and/or who works for you.
You can make all the progress you want on this. Its just a matter of how much you want to learn and how much time you want to spend learning about and working on yourself.
