I have back pain as well due to crashing the car and i use wheat bags which i stick in the microwave to warm up. I use them on my shoulders as well. You can buy them at the health food stall on the market. Another one is when mum had back pain she had a seat warmer which slipped over the back of her chair which when plugged in gave her heat on her back. She thought it was great.
