Shoulder Pain & Limited Mobility? 3 Lat Trigger Points to Check | Hadl Clinical Bodywork
X Marks the Spot: 3 Hidden Muscle Knots That May Be Limiting Your Shoulder Mobility
Shoulder pain when reaching overhead? Tightness when lifting your arm? Difficulty reaching behind your back? The problem might not be coming from your shoulder at all.
When people experience shoulder pain or limited range of motion, they often focus on the rotator cuff, shoulder joint, or upper trapezius muscles.
But there's another powerful muscle that frequently gets overlooked: the latissimus dorsi, commonly called the lats.
These large muscles extend from your lower and middle back toward your upper arms. Because they attach to the upper arm bone, they directly influence how your shoulders move.
When the lats become tight or develop sensitive trigger points, they may contribute to restricted overhead movement, pulling sensations around the shoulder, and discomfort along the side of the back.
At Hadl Clinical Bodywork in Fort Worth, Texas, we focus on understanding how muscles work together rather than looking at painful areas in isolation.
In this installment of X Marks the Spot, we're identifying three areas of the latissimus dorsi that may contribute to shoulder mobility problems—and showing you how to address them using a massage ball.
Why Tight Lats Can Cause Shoulder Mobility Problems
The latissimus dorsi is one of the largest muscles in the upper body. It plays an important role in:
- Pulling your arms downward and backward
- Rotating your upper arms inward
- Stabilizing your shoulders during lifting and pulling
- Coordinating movement between your back, shoulders, and torso
When your lats are stiff, raising your arms overhead can become more difficult.
You might notice:
- Tightness when reaching above your head
- Difficulty keeping your arms straight overhead
- Pulling sensations along your ribs or under your armpit
- Restricted shoulder movement during exercise
- Discomfort when throwing, swimming, or performing overhead lifts
Here's the important distinction: Shoulder pain doesn't automatically mean you have a shoulder injury, but it also doesn't automatically mean your lats are responsible.
Muscle tightness, joint restrictions, rotator cuff problems, and other conditions can produce overlapping symptoms.
That's why understanding the surrounding muscles matters.
X Marks the Spot #1: Below the Shoulder Blade
Location: Upper portion of the latissimus dorsi, near the lower outside edge of the shoulder blade.
The first area to investigate is the muscular tissue just below the shoulder blade, extending toward the side of the rib cage.
Sensitive points in this region may produce local tenderness and discomfort around the posterior shoulder or side of the back.
Signs this area may need attention
- Aching below the shoulder blade
- Tightness when reaching overhead
- A pulling sensation along the side of your upper back
- Tenderness when pressing the muscle
- Restricted movement during pulling or lifting exercises
How to release it using a massage ball
Wall technique
1. Stand with your back and side near a wall.
2. Place a tennis ball or massage ball against the muscular area just below the outer edge of your shoulder blade.
3. Lean gently into the ball, avoiding direct pressure on the shoulder blade and ribs.
4. Make small, controlled movements until you locate a tender muscular area.
5. Pause with comfortable pressure for approximately 30–60 seconds, breathing normally.
The goal is not to force the muscle to release. It is to reduce sensitivity and make movement more comfortable.
Afterward, slowly raise your arm overhead and notice whether the movement feels different.
X Marks the Spot #2: The Armpit and Upper Lat
Location: The muscular fold at the back of the armpit, where the latissimus dorsi approaches the upper arm.
This area is particularly relevant to shoulder mobility because the latissimus dorsi attaches to the humerus, the upper arm bone.
Stiffness here may contribute to difficulty reaching overhead, especially when the arm needs to move into full shoulder flexion.
Signs this area may need attention
- Tightness near the back of the armpit
- Difficulty lifting your arm completely overhead
- Pulling along the outer ribs when stretching
- Discomfort during overhead presses or pull-ups
- Tenderness in the muscular tissue behind the armpit
How to release it using a massage ball
Wall technique
1. Stand sideways beside a wall.
2. Raise your arm comfortably to expose the muscular fold behind your armpit.
3. Position a soft massage ball against the upper lat, slightly below and behind the armpit.
4. Apply gentle pressure by leaning toward the wall.
5. Hold for 30–60 seconds if comfortable, making only small adjustments.
Important: Avoid pressing deep into the center of the armpit, where sensitive nerves and blood vessels travel. Do not continue if you experience tingling, numbness, or shooting pain.
Test your shoulder mobility
Before and after the technique, stand with your back against a wall and slowly lift your arms overhead.
Notice whether you can reach higher without arching your lower back or flaring your ribs.
An immediate change may reflect reduced discomfort or altered muscle tension. It does not prove that a trigger point was the original cause.
X Marks the Spot #3: The Lower Lat Near the Waistline
Location: Lower portion of the latissimus dorsi, along the side of the lower back and above the waist.
Many people associate their lats only with the upper back, but the muscle has broad connections through the lower back and thoracolumbar fascia.
This relationship means that tension around the lower lat can influence how the trunk and shoulder move together.
Signs this area may need attention
- Tightness along the side of the lower back
- Pulling sensations when reaching overhead
- Restricted movement during side bending or twisting
- Discomfort along the lower ribs
- A feeling of tension connecting the lower back and shoulder
Lower-back discomfort can have many causes, so these symptoms alone do not identify a lat trigger point.
How to release it using a massage ball
Wall technique
1. Stand with your back slightly angled toward a wall.
2. Place a soft massage ball against the muscular area along the outer lower back, above the waistline.
3. Avoid direct pressure over the spine, lower ribs, or bony structures.
4. Lean gently into the ball and make small adjustments.
5. Pause on a comfortable tender area for approximately 30–60 seconds.
Use light pressure in this region rather than digging deeply into the lower back.
Afterward, test your overhead reach and side-bending movement.
How to Tell Whether Tight Lats Are Affecting Your Shoulder Mobility
Here's a simple movement assessment you can try at home.
Step 1: Test your overhead reach
Stand with your back against a wall and keep your ribs relaxed.
Raise both arms overhead as far as comfortably possible.
Notice whether you:
- Struggle to bring your arms near your ears
- Arch your lower back to compensate
- Feel pulling along the outer ribs
- Experience shoulder tightness or discomfort
Step 2: Try gentle lat self-massage
Use one of the three techniques described above, selecting the area where you notice muscular tenderness.
Keep the pressure comfortable and avoid provoking symptoms.
Step 3: Retest your movement
Repeat the same overhead reach.
Does your movement feel easier? Is the pulling sensation reduced? Can you lift your arms with less compensation?
If your movement improves, lat tension may be one contributing factor.
However, improvement after massage does not establish a diagnosis, and persistent shoulder restrictions may require further assessment.
Are Lat Trigger Points the Same as a Rotator Cuff Injury?
No.
A rotator cuff injury involves the muscles or tendons responsible for controlling and stabilizing the shoulder joint.
Latissimus dorsi trigger points refer to localized sensitive areas within the muscle that may produce discomfort or perceived referred pain.
Both can contribute to shoulder symptoms, but they require different clinical considerations.
It's also important to recognize that trigger-point identification and referred-pain maps are not perfectly reliable diagnostic tools. Research on massage and myofascial techniques suggests that some people experience short-term pain relief or improved movement, but lasting benefits and the precise mechanisms remain uncertain.
If you experience sudden weakness, significant loss of motion, numbness, pain after an injury, or symptoms that persist or worsen, seek evaluation from a qualified healthcare professional.
How Often Should You Work on Tight Lats?
Start conservatively.
Try 30–60 seconds of gentle pressure on one area, followed by comfortable shoulder movement.
You do not need to work on all three areas during every session.
More pressure does not necessarily mean better results. Aggressive ball work can irritate sensitive tissues and make symptoms worse.
For improving shoulder mobility over time, combine comfortable self-massage with appropriate stretching, strengthening, and shoulder movement exercises.

Frequently Asked Questions
Can tight lats cause shoulder pain?
Tight latissimus dorsi muscles can contribute to restricted shoulder movement and discomfort, especially during overhead reaching. However, shoulder pain has many potential causes, including rotator cuff and joint conditions.
Why can't I lift my arm all the way overhead?
Limited overhead shoulder mobility can result from lat stiffness, joint restrictions, weakness, pain, or other muscular and structural factors. An assessment can help identify the contributing causes.
Can massage improve shoulder range of motion?
Massage and other soft-tissue techniques may temporarily reduce discomfort and improve range of motion for some people. Combining treatment with appropriate mobility and strengthening exercises is generally more useful for sustained improvements.
Where are lat trigger points located?
Commonly discussed sensitive areas include the upper lat near the lower shoulder blade, the muscular fold behind the armpit, and the lower lat near the waistline. These locations are guides for exploration rather than definitive diagnostic points.
Should I use a tennis ball or lacrosse ball for tight lats?
A softer tennis ball is generally a better starting point because it allows gentler pressure. Firmer balls may be uncomfortable, particularly near the ribs and armpit.
