Back pain in general is discussed in the section Back Pain
A simple forward stretch is a great relief if you have back pain when you bend backwards. Once your healthcare provider has excluded serious problems, you can manage your back pain with this simple exercise. Each time your back hurts, spend a minute doing this forward stretch to relieve the pain. Initially you may have to do this very often, but the more you do the stretch, the better your back will get. Sometimes it can take a few days to notice a difference. Stretching and walking are the most important part of treatment. When walking, watch that your posture is correct. You can walk small distances, for short periods, even a few minutes at a time, a number of times a day, until you can walk an hour a day. Once your pain has improved, stretching should be done twice a day, after breakfast and before going to sleep.
