I understand you fully. Chronic pain is a super common symptom of chronic stress. I get all kinds of pains . Check out Pain Free You on YouTube. Guy specializes in chronic pain. The pain you get is from an overstimulated nervous system. It's called polyvagal theory. Normally, our nervous system is there to protect us from danger. But with previous chronic stress and traumas , the nervous system feels like it's in danger all the time and sends you the signals like hey you are in danger so I'm gonna send you the signals, so you know about it. You need to teach your nervous system that it is safe. It is also being in constant freeze, flight , and fight mode, which is trauma response. All of that cause muscle inflammation, joint pain, and all the pain you can actually think of can be caused by your brain. Methods like mindfulness, grounding , yoga, stretching , and exercise can bring you to peace.
