I know this is going to sound dumb.. But is sitting to low what makes you slump and hurt back or when sitting too high...
When I went to doctor with it he said I need to raise my computer on a book cause my chair was probably too high...I feel like I am sitting ok ? who knows my just be years of day after day of sewing..It got better when I quit sewing for awhile but when started work sitting at computer it was worst...Thanks everyone...quess I will sewing alittle and get up and do something else...I can't sit at church for very long and forget sitting at ball games where there is no backs at all...Guess on of those aches and pains I will have to live with...
