Understanding Muscle Spasms
A muscle spasm happens when a muscle contracts involuntarily and remains tight or painful. In the back, muscle spasms may occur on their own or as the body's response to irritation, injury, or inflammation elsewhere in the spine.
What Is a Muscle Spasm?
A muscle spasm is an involuntary tightening or contraction of a muscle. Spasms can occur in many areas of the body and may range from a brief cramp to a painful contraction that limits movement.
In the spine, the surrounding muscles help support movement and stability. When those muscles become irritated or suddenly tighten, they can cause significant pain and make it difficult to bend, twist, stand, or move normally.
Back muscle spasms may develop after overuse or strain, but they can also occur in response to irritation from another spinal structure.
The Spasm May Be a Clue
Sometimes a muscle spasm is the body's protective response to another source of pain or irritation in the spine.
Why Can Back Muscles Spasm?
Muscles surrounding the spine may tighten in an attempt to protect an area that has become strained, injured, or irritated.
Spinal Irritation
An irritated joint or other spinal structure may trigger a protective muscular response.
Muscle Tightening
Supporting muscles may contract involuntarily around the painful or irritated area.
Reduced Movement
Tight muscles can restrict normal movement of the neck or back.
More Pain
Persistent tightness can contribute to additional soreness, stiffness, and difficulty moving comfortably.
Can Facet Joint Problems Cause Muscle Spasms?
They can. The facet joints are small joints along the back of the spine that help guide and stabilize movement.
When a facet joint becomes injured, irritated, or inflamed, the muscles surrounding the spine may tighten in response. This protective reaction can create both pain and limited movement.
This is one reason determining the underlying source of a muscle spasm can be important rather than treating the tight muscle alone.
What Does a Back Muscle Spasm Feel Like?
Symptoms can vary depending on which muscles are involved and what caused the spasm.
Sudden Tightness
A muscle may suddenly tighten, contract, or feel as though it has "locked up."
Aching or Sharp Pain
Spasms can cause a deep ache, cramping sensation, or more intense pain with movement.
Restricted Movement
Turning, bending, standing upright, or changing positions may become uncomfortable.
Muscle Tenderness
The affected muscles may feel tight, sore, tender, or sensitive to pressure.
Why Is the Muscle Spasming?
Treating the tight muscle may provide relief, but persistent or recurring spasms may require a closer look at what is triggering the muscle to contract in the first place.
Detailed pain and injury history
Physical examination
Movement and range-of-motion testing
Evaluation of spinal joints and muscles
Evaluation for nerve-related symptoms
Imaging or additional testing when appropriate
Your provider will consider the complete picture to determine whether the muscle spasm appears to be the primary problem or a response to another condition.
How Are Muscle Spasms Treated?
Treatment depends on what is causing the spasm, how severe the symptoms are, and whether another spinal condition is contributing to the problem.
Medication
In appropriate cases, medications such as muscle relaxants may be used to help reduce painful muscle spasms.
Exercise & Therapy
Gentle stretching, movement, strengthening, and physical therapy may help restore normal motion and reduce recurring strain.
Heat
Heat may help relax tight muscles and temporarily reduce stiffness or discomfort for some patients.
Treating the Underlying Cause
If another condition is triggering the muscle spasm, addressing that condition may be an important part of long-term relief.
Look Beyond the Tight Muscle
Recurring back spasms can sometimes be a sign that another structure in the spine is irritated. Utah Spine & Pain evaluates both the muscle spasm and the potential underlying cause to help determine the most appropriate treatment plan.
