Hi there! -
Moving pain to me means local pains that can very often be tackled individually, in my case all of them could and can.
I'm pretty sure they "move" or "alternate" because when we adjust our posture to one that may be easier on that, but cause problems elsewhere because the "root" in the muscles, tendons, fasciae etc. hasn't been ironed out.
Either by good gentle listening physiotherapists who can do things like acupressure, osteopathy, myofascial, Scar- and Bonework, trigger pointing and all the other techniques
Or by trying out all the many exercises, stretches and acupressure videos for each single pain as soon as it twinges.
Or both.
Just had it this week again, suddenly 3 old pain areas cropped up due to the cold & damp, maybe even due to trying whole body cryotherapy again: My neck tightened, my clavicle and shoulder and my right knee. Because I tackled them all immediately and also now know several tricks that got them down the last times, I got them down inside of a few hours. For my clavicle various stretches every hour and for my knee my massage 'gun', for my neck a combination of both.
Of course all of these have to be compatible with the herniated discs. If you look exercises & stretches for those you will find for instance DoctorJo, Bob & Brad which are both often fairly good, and Back Intelligence tells you what exercises to do and in another video what not to do....
Once you've carefully got that under control more, you can tackle the back & neck pain. And as soon as those are better check if any of the older pains need a bit of preventative stretching. Often we can feel that those muscles & tendons aren't as flexible as they should be even before the pains start.
