It is so possible to damage the body doing hand work too. I sewed a queen grandmother's flower garden quilt and damaged both my hands. It has been months and the tendons in the left hand (holding hand) are still painful. Doctor is not much help. In fact, I was so mad at her, I am thinking of changing doctors.
After a retreat, it took over a week to get over the pain. The neck and back revolted and let me know how unhappy they were. I must have been ignoring them the whole week. Thought I had stopped enough but the bad chair and height must have been worse than I thought. Next time I am bringing my own chair.
I am going to try some of these remedies.
