I do have scoliosis, but issues were purely with muscles.

Well, I’m not sure how that’s called, like stretching neck muscles, doing different exercises with elastic rope that loads neck and spine, and such. It seems to be different complex with every other practitioner that’s teaching what to do, but what worked best for me is standing on elastic rope holding it in both hands and lifting hands to T-pose (not an advice, consult a medic insted)
