Thigh Pain Causes
Tension in the muscle
groups on the back of the thigh is extremely
common. If left unaddressed, this tension will
often lead to painful stiffness that is experienced
in the back of the thigh region. Occasionally this
muscle group will suffer "charlie horse" cramping
episodes. The abnormal tension that inflicts these
muscle groups will often predispose athletes to
hamstring strains or tears.
The
Muscles and Trigger Points that Cause Thigh Pain
& Cramps
The three muscles
groups that are frequently involved with back of
the thigh pain and tension are:
-
The Semitendinosus and
Semimembranosus
-
The Bicep Femoris
-
The Gluteus Minimus
The
Semitendinosus and Semimembranosus
muscles are two of the three muscles that comprise
the Hamstring group. These muscles attach to the
lower pelvis and run downward to attach to the
lower leg just below the inside of the knee. These
muscles function to keep the trunk erect when
standing, and to flex the leg at the knee. Trigger
points in these muscles refer pain to the back of
the thigh, lower buttocks and back of the knee
regions. People with active trigger points usually
experience pain while walking, causing them to
limp. Trigger points in these muscles may also
contribute significantly to knee pain
disorders.
The
Bicep Femoris
is part of the Hamstring muscle group that is found
on the back of the thigh. It attaches on the pelvic
bone and the femur (thigh bone), and extends
downward to attach to the smaller lower leg bone
(the fibula) just below the outside aspect of the
knee joint. When the Bicep Femoris muscle
contracts, it flexes the knee to bend the leg. It
is heavily used in walking, running and other
activities. Trigger points in this muscle refer
pain to buttock, back of the thigh, and back of the
knee regions. Additionally, they may cause "charlie
horse" type cramping episodes. The pain is felt
during walking, sitting, and may disturb sleeping.
The muscle weakness created by these trigger
points, will frequently cause the other thigh
muscles to become overloaded and develop their own
trigger points.
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. Gluteus Minimus
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
in the
Quadratus
Lumborum
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
back pocket. The posterior trigger points,
typically three or four in number, refer pain to
buttocks, back of the thigh, and calf
regions
