Laser Therapy for Sciatica
What is sciatica?

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).
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.
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.
