I have developed a sore back. I am not sure how or why. I have an appointment to see a chiropractor next week. It isn't extremely painful. I guess the problem is mostly just an unusual sensitivity, one that I am sensitive to and somewhat fearful of. I don't want it to get worse.
My usual practice has been to sit with a heating pad on my back. Doing that seems to help. I am not sure if the total time and discomfort is diminished with a pad or not.
