Sciatica pain is caused by the irritation of the sciatic nerve due to an excessive growth of a bone or a disk affected by a hernia, as stated by Mayo Clinic. There are also other factors that might lead to the pain, including pregnancy, degenerative disc disease, lumbar spinal stenosis and spondylolisthesis.
The pain may worsen from several other factors, such as putting on high heels, sleeping on a soft mattress, lack of exercise and being overweight, as according to WebMD. Sciatica is a type of pain that occurs on the sciatic nerve, which starts at the lower back and goes down to each leg.
The common symptoms of sciatica include shooting pain, a burning sensation down the leg, numbness, weakness and pain that affects the rear. This condition tends to affect a particular side of the lower body. Some cases of this pain can be severe, but can clear up after a few weeks of treatment.
Sciatica may affect people differently as it can be potentially worse in some patients. Depending on the location of the pain on the nerve, the pain may reach the toes or foot, notes WebMD. Treatment is required if the pain causes numbness in the thighs and excessive weakness.
