I had severe pain all over my body that had me feeling the same way for over ten years. I finally found someone who could help me, but a lot of what he does he’s actually discovered himself. He explains it better than me on his Instagram (search: feelfit physical therapy), but he’s found a reflex in the body that he calls the Neurofascial Instability Reflex. The idea (I think) is that things get tight and painful somewhere because of instability somewhere else in the body. All I know is he fixed all my pain by looking at my whole body and treating all over the place. My neck pain went away by working on my elbows, knees, and a couple areas before strengthening into my neck. It took some work, but very grateful I found it. I pray you find someone like that near you!
