I tend to develop bad lower back spasms-where my muscles knot up into a painful ball and my back between my shoulder blades becomes very sore and painful if I sew regularly.
I've gone to a chiropractor who helped quite a bit to get rid of the pain. but I want to be able to sew like I used to-several hours a night.
I can only sew for about 15 minutes before I start to feel the discomfort.
I've tilted my sewing machine forward some. Bought a sewing table instead of using a computer desk so it's lower, My chair is adjustable and I think it's at the right height.
I focus on good posture, block my core muscles so I'm not slumping and putting pressure on my lower back muscles.
What has helped you that I haven't tried?
