Thanks, Signed, Aching Back Dear Aching Back, Alice can't diagnose your problem over the computer, as Alice has told others before you. Back problems are often a sign of stress. You might also want to work on ways to reduce the tension in your life, as well as making yourself more physically comfortable. Definitely change your regular chair, carry comfortable cushions for long car or train rides, take baths, and work on your posture. Try small amounts of aspirin, and check out Arnica in a health food store.
Arnica is an herb known to be a muscle relaxant.
None of these will cure the problem, but might help to make you more comfortable until you find the real cause.
