Quite often leg pain or foot pain is not caused by a problem in the leg or foot, but rather by a condition in the lower back. Diagnosis of leg pain and other lower extremity symptoms should focus not only on the legs and hips, but should also include examination of the low back. In fact, with many low back problems, there is actually little or no low back pain. Instead, there may be leg pain, foot pain, and/or lower extremity numbness or weakness.
