The sciatic nerve is the largest nerve in the human body, measuring three-quarters of an inch in diameter and reaching from the spinal cord in the lower back down through the feet.
Function of the sciatic nerve
The sciatic nerve allows a person to have movement and feeling in his toes, feet, ankles, knees, thighs, hips and lower back.
What is sciatica?
Sciatica causes sharp pain, numbness or tingling in a patient's lower back or legs due to pressure being put on the sciatic nerve. This can be caused by muscle inflammation, a herniated disc in the spinal cord or a tumor.
Medicines
A commonly effective treatment for sciatica is regular use of anti-inflammatory medicines. These medicines allow for better circulation and take pressure off of the nerve to relieve pain and increase mobility.
Daily habits
Activities that increase pain should be avoided. Sitting for long periods can be detrimental. Frequent walks of increasing lengths can promote the improvement of sciatica. Massage will also relieve discomfort.
Surgery
In extreme cases, surgery may be necessary to remove tumors or realign spinal discs. A doctor will decide if surgery is an appropriate option for a patient.
