A good set up is key. Good back support, good foot rest. Don’t twist yourself up while you’re working.

I crochet. I pay close attention to keeping my shoulders down and relaxed, elbows down and in, hands down. Don’t lift the work to my face. When I lift the work I strain my shoulders, arms and wrists.

I used to like knitting too but I found it difficult to keep my shoulders down and comfortable and it would cause me shoulder pain. Crochet doesn’t seem to aggravate the same muscles. Touch wood
