What is Sciatica and How its Treated
Sciatica is a condition involving pain, weakness, numbness, or tingling in the leg. It is caused by injury to or compression of the sciatic nerve.
Sciatica is a form of peripheral neuropathy. It occurs when there is damage to the sciatic nerve, located in the back of the leg. This nerve controls the muscles of the back of the knee and lower leg and provides sensation to the back of the thigh, part of the lower leg and the sole of the foot. Incomplete damage to the sciatic nerve may appear identical to damage to one of the branches of the sciatic nerve (tibial nerve dysfunction or common peroneal nerve dysfunction).
The main nerve traveling down the leg is the sciatic nerve. Pain associated with the sciatic nerve usually originates higher along the spinal
cord when nerve roots become compressed or damaged from narrowing of the vertebral column or from a slipped disk. Symptoms can include tingling, numbness, or pain, which radiates to the buttocks legs and feet.
The sciatic nerve is commonly injured by fractures of the pelvis, or other trauma to the buttocks or thigh. Prolonged sitting or lying with
pressure on the buttocks may also injure it. Systemic diseases, such as diabetes, can typically damage many different nerves, including
the sciatic nerve.
Note: A ruptured lumbar disk in the spine may cause symptoms that simulate the symptoms of sciatic nerve dysfunction.
How does Laser Therapy treat sciatica?
Laser Therapy will increase circulation, enhance the formation of new blood and lymphatic vessels and nerve endings and reduce edema. It will increase the activity and numbers of fibroblasts, cells which produce collagen, the forerunner of cartilage. Other formative cells are
also positively influenced. One of laser therapy’s many immune enhancing effects is an increase in the number and activity of macrophages.
How many treatments will I need?
Patients frequently report an absence of pain after laser treatment. A large part of this may be due to the anti-inflammatory effect of laser therapy as increased circulation and lymphatic drainage reduce edema and pressure on the nerves. Some of the many other reasons for analgesia include elevated levels of endorphins, electrolytic nerve blockade, cellular membrane hyperpolarization and the restoration of blood flow to the areas of stagnation to correct ischemia and acidosis. How many treatments needed will depend on how your body responds, and the length and severity of the injury. Although many people can experience pain relief rather quickly, the underlying cause will require a series of treatments.
