I love to sew, and I hate it when things get in the way of it.
I have developed some pretty severe shoulder pain in my left shoulder. It has gotten to the point that it makes it very hard for me to sew at times. I went to my doctor, and she thinks that I have either developed a bursitis, or I have damaged the muscle that leads up the back of my arm and into the joint. All I know is that it hurt like crazy, and I don't like to take a lot of pills. Ice works until I take it off. You can't sew with an ice pack on your shoulder!
I have medicine for it that I can take if I want to, but I am also wondering if I am doing something with my posture that may be irritating this. How do you generally sit at your machine? Is there something ergonomic that you do?
