A combination of five nerve roots from the lower spine help in the formation of the human body’s largest nerve, known as the Sciatica. It travels to the sole and heel of the foot, passing through the buttock and back of the thigh. It helps connect the muscles and skin of the thigh, leg and foot with the spinal cord. Any inflammation, ache or neurological condition that originates from the nerve is known as Sciatica. The problem lies in the lower back, which results in irritation or compression of the sciatic nerve. Certain factors can trigger the condition resulting in varied symptoms in different patients.

What factors can trigger Sciatica pain?

The bulging of a disc in the lower back can cause the sciatic nerve root to compress, resulting in herniated discs. Thickening of the facet joint capsules can cause degenerative changes in the spine, causing foraminal stenosis. Segmental instability due to slip disc, vertebral defects or complete dislocation of the vertebrae may result in mechanical compression of sciatic nerves. The compression can also happen due to a cyst, infection or tumour, but that is a rare scenario. Tall elderly individuals or individuals with obesity is a potential candidate for sciatic conditions. Other than these, generic factors, vitamin B12 deficiency, professional hazards, and chemical inflammation can be important.

What are the symptoms?

Pain indicating nerve irritation or inflammation is the main symptom of Sciatica pain [ปวด สะโพก ร้าว ลง ขา]. You may rarely experience difficulty in both legs. The effect of the pain is generally on any one leg, or it may be an alternating process. The nature may vary from a repetitive, dull ache to a throbbing or shooting pain in stints. The neurological symptoms include weakness in thigh and foot muscles and numbness in the calf, heel, sole or top of the foot. You may feel difficulty in bringing the thighs together and bending your knees. The conduction of the nerve becomes improper, resulting in an abnormal sensation on the skin.
