Many who knit, crochet, spin, weave, or do similar crafts, can have hand, neck, and shoulder issues. As a massage therapist, I would suggest that you try to find a good massage therapist that is familiar with trigger point therapy. It provides great relief and with a minimal amount of hands on instruction you can learn how to do it on yourself. I regularly work the trigger points in my arms and hands, (caused by both knitting and by doing massage) I teach my clients to do the same. Massaging a joint gently will help it produce more synovial fluid, which helps to cushion the joint. Try massaging between the bones on your hands, a good soak in warm water can sometimes bring temporary relief. Hope that helps some.
