Causes of Sciatica
is a non-specific term that describes pain (and/or
numbness or tingling sensations) that travel from
the buttocks down the back (or side) of the leg.
Sciatica symptoms can have various causes.
Typically, this type of pain is generally
associated with the compression of the sciatic
nerve by a damaged or prolapsed spinal disc. This
situation is very serious and produces a pain that
is nearly constant and unbearable. Surgery is the
only viable option in this situation.
pain or numbness that "comes and goes" with your
activities and body position, suggests that a
muscular source is the cause, and not a disc
herniation. Trigger points in the buttock and hip
regions can easily produce sciatica symptoms.
Typically, trigger point produced sciatica symptoms
occur secondarily to a previous (or concurrent) low
back or hip pain disorder.
Muscles and Trigger Points that Cause
in the following two muscle groups can produce
The Gluteus Minimus
is a small, fan-shaped muscle group that lies deep
in the buttock region, just above and behind the
hip joint. It attaches to the pelvic bone and runs
downward to attach to the thigh bone (the femur)
near the hip joint. Like the larger Gluteus Medius
muscle group that lies over it, the Gluteus Minimus
functions to stabilize the pelvis during walking
and other upright activities.
trigger points can refer pain to the hip joint,
buttocks, down the back of the leg to the calf, and
down the outside of the leg to the ankle. These
trigger points can be activated by trigger points
muscle group, by long periods of immobilization, or
by the abnormal body mechanics that are created
when a person must limp for any reason.
Additionally, men may activate these trigger points
by sitting on a large wallet that is kept in the
points in this muscle can be divided into two
groups. The posterior trigger points, typically
three or four in number, refer pain to buttocks,
back of the thigh, and calf regions. The lateral
trigger points lie directly above the hip joint and
refer pain to the outside buttock, hip joint,
outside thigh, and lower leg regions.
muscle is a short, small muscle that is located
deep in the buttock region. It functions to rotate
the thigh, and helps to stabilize the hip joint
during walking. This muscle lies next to a major
nerve (the Sciatic Nerve) and blood vessels.
Trigger points in this muscle can cause it to
become tense enough for it to entrap or compress
the nerve and blood vessel, producing systems such
as pain, numbness, and swelling that travel down
the leg from the gluteal region. When this
entrapment occurs, it is termed
Clinical studies suggest that sciatica symptoms are
cuased by Piriformis syndrome more often than they
are caused by a spinal disc rupture or prolapse.
Piriformis trigger points may refer pain to the
Sacro-Iliac Joint, buttock, and hip joint regions.
This referred pain may occur with the other
symptoms created by entrapment of the sciatic
