Suggest Treatment For Muscles Pain In Back/neck/shoulders While Having Scoliosis

I have a slight scoliosis problem... I go to see a chiropractor to help realine my spine a bit. It seems to be helping but i still have alot of back pain whenever there is pressure against it for too long. Almost all of the muscles in my back, neck, and shouldars ache to the touch and it is very annoying to have to live through everyday. For example- I'll be sitting in the car against a carseat and my back will start hurting. I would then have to move every which way until i can find a comfortable position for my back that may not be comfortable for the rest of my body. It then takes a few minutes to stop hurting again. Is there anything I can do to help these aching muscles??
