A hot bath with magnesium salt seems to help me sometimes. It might be worth a try. Supposedly magnesium chloride salt is more effective than epsom salt. Put about two cups of salt in a tub full of hot water and soak for at least twenty minutes. Often my body feels extremely relaxed after doing this.
Another thing that sometimes works for me is to just lie down and rest/nap for 10-15 minutes.
Something that seems to keep pain flares away for me is regular long-duration light exercise. If the pain isn't too bad, and I can get in 1-2 hours of walking, shooting a basketball, etc., my pain levels tend to drop. Doing this several days in a row really seems to help. I have not been as good about this with the colder weather lately and am feeling it the last few days.
