I also have back pains. But the one that bothers me the most is the sharp pain running from the right side of my neck down my scapula (shoulder blade). I was told once that every hour or so you should stop sewing and do shoulder shrugs...lift your shoulders up towards your ears and down again. Also rotating your shoulders frontwards and backwards and moving your head in a circular motion to the right and the left is also helpful. Thanks to all for their suggestions.
