The occurrence of pain in the lumbosacral or the lower portion of the back is the most prominent and common symptom of low back pain. The pain which starts from the lower back may spread either to the leg in front, side or back or it may just remain in the lower back depending upon the severity.
By doing more physical activity the pain may even get to worse conditions but some physical activity should always be done to prevent the loss of flexibility of back. The pain may increase when the body remains in a single posture for a long period of time like at night or prolonged sitting (e.g. in a long car or bus drive). So this should always be avoided for preventing the worsening of the pain.
The back pain always occurs due to compression of some or a single nerve of the back, so, the region of leg which receives the compressed nerve may experience weakness or numbness which is also a major symptom. When the first sacral nerve of the back gets compressed, the leg experiences problem like inability to stand on the toe or to raise or bring down the foot. When the fifth lumbar nerve is compressed, there is problem with raising the big toe on the upward side.
The lower back pain which occurs through the injury of the muscles or ligaments of the back generally have the nature to remain only in the back in place of spreading to legs as in other conditions. Due to injury there may be problem in the movement of back depending upon the extent and type of injury.
The main symptoms which occur in the condition of herniated disc which is due to compression of sciatic nerve are:
1. The pain occurs on the legs or hips or it may also be tangling in these regions. Generally the pain which occurs in this case is mild in nature.
2. When the person undergoes sneezing or coughing, the pain may even get worsen.
3. By sitting or standing for a long period of time with or without the change in posture may also lead to worsening of the pain.
