Topic Overview
What is myofascial pain syndrome?
Most people have muscle pain from time to
time. But myofascial pain is a kind of ongoing or longer-lasting pain that can
affect the connective tissue (fascia) of a muscle or group of muscles. With
myofascial pain, there are areas called trigger points. Trigger points are
usually in fascia or in a tight muscle.
When you put pressure on
a trigger point, you not only feel pain at the trigger point but you may also
feel it in muscles in another area. For example, pressure on a trigger point in
the neck may cause pain in your arm. This is called referred pain.
Myofascial pain often goes away with treatment.
What causes myofascial pain syndrome?
Experts
don't know exactly what causes myofacial pain syndrome. It may start
after:
- Strain or injury to the muscles,
ligaments, or
tendons.
- Overuse, such as from typing on
a computer or writing at a desk.
- Using a muscle after you haven't
used it for a while, such as after a stroke or after having a broken
bone.
What are the symptoms?
The main symptom of myofascial pain syndrome is ongoing or longer-lasting
muscle pain, in areas such as the low back, neck, shoulders, and chest. You
might feel the pain or the pain may get worse when you press on a trigger
point. The muscle may be swollen or hard—you may hear it called a "taut band"
of muscle or "knot" in the muscle. Symptoms of myofascial pain may include:
- A muscle that is sensitive or tender when
touched.
- Muscle pain that happens with pressure on a trigger
point.
- Pain that feels like aching, burning, stinging, or
stabbing.
- Reduced
range of motion in the affected area.
- A
feeling of weakness in the affected muscle.
People with myofascial pain syndrome may have other health
problems, such as
tension headaches,
depression, sleep problems, and
fatigue. These problems are common in people who have
chronic pain.
How is myofascial pain syndrome diagnosed?
To diagnose myofascial pain syndrome, your doctor
will ask if you have had a recent injury, where the pain is, how long you have
had the pain, what makes it better or worse, and if you have any other
symptoms.
The doctor will also give you a physical exam. He or
she will press on different areas to see if the pressure causes pain. If
pressure on a certain area causes your pain to get worse, this means that the
doctor has found a trigger point for your pain. Your pain may be in a different
spot than the trigger point.
You may have tests to see if some
other condition is causing your pain.
How is it treated?
Talk to your doctor about the best way to treat
your pain. The main treatment may include any of the following:
- Spray and stretch. This involves using a
cooling spray directly on the skin from the trigger point to the painful area
and then gently stretching the muscle. This may be repeated several
times.
-
Physical therapy, which may include stretching and
strengthening exercises. It may also include counseling about how to change the
things that make the pain worse. For example, you may learn how to adjust your
workstation, improve your posture, or change your sleep position to avoid
muscle tension.
- Massage.
-
Ultrasound.
- Trigger point shots
(injections). A doctor inserts a needle into the trigger point and injects
medicine such as a
local anesthetic.
Your doctor may also recommend
nonsteroidal anti-inflammatory drugs (NSAIDs), such as
ibuprofen or aspirin. These medicines may help with your symptoms.
Sometimes doctors prescribe certain antidepressants or muscle relaxants
that help relax muscles and relieve sleep problems related to myofascial
pain.
Some people with myofascial pain also find complementary
therapies helpful. These include
acupuncture, massage,
behavioral therapy, and relaxation techniques.
