I have lower back pain and right calf down to leg pain and also dark yellow urine, what are the possible symptoms and solutions so that i could be well again? also i'm having a hard time walking for a long period of time and waking up in a leg pain?

Radiating leg pain: When a nerve is "pinched" in the lower back, the pain would radiate along that nerve's path, most of the times to the toes. This can happen if a disc is damaged in the lower spine. Dark urine is not related to these symptoms but a sign of dehydration. Drink more water for sure. Avoid prolonged sitting, bending, heavy lifting etc to give the disc a chance to heal.
