I have had back pain since I broke it in '89. Here are a few tips:
1. Have a small child walk on your back (this usually costs at least a quarter)
2. Get spouse to rub your back (if you are female, you may find bruises and consequently won't ask for this favor again)
3. Hot shower or better yet, hot tub with epsom salts, candles and a glass of wine.
4. Ice, later heat
5. Tiger Balm
6. Usually this is a good time to walk through parking lots, as you are much closer to the ground and can easily spot fallen coins.
Next year, tie horse to tree, or hire teenagers.
Hope you feel better soon!
