Causes of Groin Pain
Groin pain is
typically a disorder common in athletes, but it
also may occur as a secondary pain syndrome to low
back or hip pain disorders. The pain associated
with a groin pull may or may not be produced by
trigger points. If the muscle groups in the groin
region were overloaded by an injury, then it is
likely that trigger points developed in these
muscles. It is common for trigger points in these
muscles to continue to produce pain long after the
original muscle strain has healed. This is one
reason that athletes typically take a long time to
completely recover from this type of injury.
The
Muscles and Trigger Points that Cause Groin
Pain
As many as five
muscles can contain trigger points that refer pain
to the groin or inside thigh region. The following
three muscle groups are the most frequently
involved:
-
The Adductor Magnus
-
The Quadratus Lumborum
-
The Abdominal Obliques
The
Adductor Magnus
is a large muscle group found deep in the inner
thigh region. This muscle attaches to the pelvis
and runs downward to attach at several places along
the large thigh bone (the femur). This muscle
contracts to rotate and swing the thigh inwardly
(towards the other leg). Trigger points in this
muscle can refer pain to the groin or inner thigh
region. One particular trigger point may also refer
pain that is felt inside the pelvis, genitalia, or
rectum. This trigger point is frequently active
during times of severe menstrual cramping. This
muscle group is typically injured during a groin
pull or strain.
The
Quadratus Lumborum
muscle group is composed of several small muscles
that are located deep within the lower back muscle
mass. It attaches to the lowest rib, at several
spots along the lower (lumbar) spine, and along the
pelvic rim. The Quadratus Lumborum contracts to
help stabilize the spine, and to flex the trunk to
either side. This muscle group can contain up to
four trigger points that refer pain to the low
back, groin, hip, and gluteal regions. A person
with active Quadratus Lumborum trigger points will
typically experience severe pain when their trunk
is in an upright position. Often they will
instinctively brace and support their upper body
with their arms to avoid this severe pain.
Alternatively, they may be forced to move about on
all fours. Coughing and sneezing produce agonizing
pain. Referred pain from Quadratus Lumborum trigger
points may activate other trigger points that in
turn produce sciatica-type symptoms.

Points: Masters of Low Back Pain
The
Abdominal
Oblique
muscles form the outer abdominal wall in the
stomach region. They attach to the ribs, pelvis,
and to other abdominal muscles via a large sheet of
connective tissue. This muscle group contracts to
stabilize the trunk, and to flex and/or rotate the
trunk to either side. Trigger points in this muscle
group can refer pain to the lower abdomen, groin,
and genitalia. They may also produce diverse
symptoms such as heartburn, abdominal bloating,
belching, and diarrhea.
