Causes of Elbow Pain
Trigger
point produced elbow pain is often mistaken as
"tennis elbow", "golfer's elbow", or tendonitis.
The forearm muscles are easily overloaded by
popular sports and repetitive work activities. In
addition, muscle groups in the shoulder region can
contain trigger points that refer pain to the
elbow.
The
Muscles and Trigger Points that Cause Elbow
Pain
There are six muscles that can contain trigger
points that refer pain to the elbow. The three most
commonly affected muscle groups are:
-
The Triceps Brachii
-
The Supinator
-
The Brachioradialis
The
Tricep Brachii
muscle group is located on the back of the upper
arm. It attaches to the upper arm bone (the
humerus), the shoulder blade, and the inside
forearm bone (the ulna). When you straighten your
arm, you contract the Triceps muscle to do so. This
muscle group can contain up to five trigger points.
Referred pain from theses trigger points is
experienced on both the inside and outside aspects
of the elbow joint, as well as in the rear shoulder
region. Pain from these trigger points typically
occurs when a person tries to forcefully straighten
the arm, like when performing a back hand stroke in
tennis.
The
Supinator
muscle group is a small, flat muscle that wraps
around the outside aspect of the elbow joint. This
muscle contracts when you rotate your forearm, like
when you make a thumbs-up gesture. The trigger
point in this muscle refers pain to the outside
aspect of the elbow joint. Sometimes the pain will
also be experienced in the web of the thumb. In
general, the pain occurs during activities like
playing tennis, or carrying a heavy
briefcase.
The
Brachioradialis
muscle group is a long, thin muscle that attaches
to the upper arm bone (the humerus) and to the two
forearm bones (the radius and ulna bones). This
muscle contracts to flex the elbow (bend the arm).
Much like the Supinator muscle, the trigger point
in the Brachioradialis refers pain to the outside
aspect of the elbow joint, and sometimes to the web
of the thumb. A person with an active trigger point
in this muscle would feel pain and weakness as they
reached to grasp something, like a door knob, or to
shake a hand.
