Tennis Elbow Hidden Cause: Neck Dysfunction
Key insights: 60-second read
- Tennis elbow is often a consequence of neck dysfunction, not just an isolated elbow problem - hidden stiffness at the base of the neck and top of the upper back can create the cascade that leads to lateral elbow pain.
- You may have no neck pain at all - the dysfunction can be completely silent, with elbow symptoms being the only sign.
- Test-retest proves the connection - if releasing your neck changes your elbow symptoms, you have found a potential root cause.
- Three-pronged approach: neck, nerve, local tissue - address the hidden neck dysfunction, glide the radial nerve, and release local tight tissue.
- Your daily posture is the hidden driver - looking down and rolling your shoulders forward creates the neck dysfunction that sets up your elbow for trouble.
If you have been dealing with tennis elbow (lateral epicondylitis) and nothing seems to work - rest, ice, bracing, massage, injections, even surgery - you may be missing the hidden root cause.
In my work as a physiotherapist, I have found that the overwhelming majority of lateral elbow pain is set up to be there because of hidden neck dysfunction. The nerves that supply the muscles and tendons of your forearm come from your lower cervical spine (neck). When those spinal segments become stiff, tight, and overloaded, they can change how your elbow functions - often without any neck pain at all.
This video and article will show you how to test this connection for yourself and give you a three-step approach to address both the symptoms and the root cause.
"The overwhelming majority of lateral elbow pain or lateral epicondylitis symptoms are set up to be there because of more obscure, relatively hidden neck dysfunction. We are looking at mechanical dysfunction at the levels of the neck that have the nerves that run down through that area."

The neck test: find the hidden dysfunction
Before you do anything, you need a baseline. Perform a movement or activity that alerts you to your elbow symptoms - making a fist, twisting something, or gripping.
What you need: A lacrosse ball, tennis ball, or similar firm object.
Step-by-step:
- Place the ball at the base of your neck (the prominent bump at the bottom of your cervical spine). Let it roll off to one side.
- Lie down on the ball (or lean against a wall if you prefer). You may need to roll your neck, shoulders, and body to that side to get pressure onto the ball.
- You are looking for tissue that feels stiff, tight, restricted, thick, or dense - especially compared to the same spot on the other side.
- The key: It may not be tender. You do not need to have neck pain for this to be relevant. The side that feels more restricted is the side you need to work on, regardless of which elbow hurts.
- Stay on each tight spot for 30-60 seconds. Take slow, deep breaths to help the tissue relax.
- Systematically work your way up and down the neck, hitting each joint level.
Re-test: Immediately repeat the movement that previously triggered your elbow symptoms. Has anything changed? If your symptoms improved even 10-50%, you have just proven that your neck is involved.
The key insight
"We are not necessarily as interested in which side of your neck as much as the level that is dysfunctional. Trust what you find."
Radial nerve glides: freeing the cable
The radial nerve runs from your neck, under your armpit, down the back of your arm, and past the outside of your elbow. If there is any restriction or tension along this path, it can contribute to tennis elbow symptoms.
Important principle: Neural tissue does not stretch. We are not trying to lengthen the nerve. Instead, we are flossing it - moving it back and forth through the surrounding tissues to restore normal glide.
How to perform radial nerve glides:
- Stand up tall with good posture, arms by your sides.
- Bend your wrists back (extend them) and point your hands out at about 35-45 degrees (not straight back).
- Gently swing your arms backwards and forwards in a 45-degree arc through the front of your body.
- When you bring your arm fully back, you should feel a light tension or pulling through the top of your forearm or the side of your elbow.
- Do not push into pain - work within a comfortable range.
- Perform 15-20 slow, controlled swings. Your range should improve as you go.
- For a more challenging version, bend and straighten your elbows as you swing.
Re-test: After completing the nerve glides, repeat the movement that triggered your symptoms. Has your elbow pain changed?
"We are not trying to stretch the nerve. We are trying to floss that neural tissue through all the channels that they pass through and should pass through comfortably."
Self-massage and local tissue work
Once you have addressed the neck and the nerve, it is time to work on the local tissue around the elbow itself.
Manual massage:
- Use moisturiser or massage cream.
- Gently massage the forearm muscles, especially as they form into the tendon that attaches to the outside of your elbow.
- Do not forget to work above the elbow - the radial nerve hooks through the back of your tricep, and tightness there can also contribute to your symptoms.
Ball massage:
- Roll the ball over any tight spots.
- For a trigger point release, find a tight spot and hold the ball there for 30-60 seconds.
- For a more active release, keep the ball on the tight spot and move your wrist (bending it back and forth, turning your palm up and down) to shear the tissue free.
Re-test: Once you have spent some time releasing the local tissue, repeat the movement that triggered your symptoms. Has anything changed?
Local tissue tip
"Make sure that you also come above the elbow. Any tightness in there does not have to be there. We can use movement to try and shear that tissue free."
The posture connection: why it happens
You have now identified that your neck is involved. But if you do not address why your neck became dysfunctional in the first place, the tennis elbow will likely return.
Clinically, the most common cause is prolonged poor neck posture - looking down, dropping and rolling your shoulders forward while working at a computer, using a phone, reading, driving, or sitting on the couch. These positions create a hinge point in your neck, overloading specific spinal segments day after day.
Tennis elbow is not an overuse issue - although it can present that way. We know using our tissue is normal. The problem often lies with the hidden dysfunction that constant use, gripping, or typing eventually exposes. If there were no dysfunction, using your tissue should not ideally cause a problem.
What you can do:
- Become taller with your shoulders comfortably back more often.
- Arrange your desk, chair, and workstation to support this shape.
- Take frequent breaks from sustained neck flexion.
- Consider a standing desk or alternating positions.
From my clinical experience
In 20 years of practice, I have seen countless patients with tennis elbow who have tried everything - rest, ice, bracing, massage, injections, even surgery - and the pain keeps coming back. Why? Because no one looked at their neck.
Your tennis elbow is a consequence of something else. The local tendonopathy, tear, or nerve irritation is very real. But it is the consequence, not the cause. The cause is hidden neck dysfunction that changed how your elbow was loaded.
If you try these exercises and your elbow symptoms change, you have proven the connection. Now you need to address both the symptoms and the cause. And the cause is almost always the daily shapes and positions you put your neck into most throughout the day.
One key insight from this video
"Tennis elbow is often a consequence of hidden neck dysfunction, not an elbow problem. The nerves that supply your forearm come from your lower cervical spine. When those segments become stiff and overloaded, they change how your elbow functions - often without any neck pain at all. A simple lacrosse ball test can prove the connection."
Frequently asked questions
How do I know if my tennis elbow is coming from my neck?
The test-retest method in this video is your answer. If you release the stiff spots in your neck with a lacrosse ball and your elbow symptoms change (improve or worsen), your neck is involved. If nothing changes, your tennis elbow may be coming from a different source.
Can I still use my arm while I am working on this?
Yes. The goal is not to stop using your arm entirely. However, you may need to temporarily modify activities that aggravate your symptoms while you address the underlying neck dysfunction. The key is to treat the cause (the neck) while managing the symptom (the elbow).
How often should I do these exercises?
Daily is ideal, especially when you are first identifying the connection. Spend 2-5 minutes on the neck release, 1-2 minutes on nerve glides, and 2-3 minutes on local tissue work. Use the test-retest method to track your progress.
What if I cannot find any tight spots in my neck?
It may be that your neck is not involved, or the dysfunction is subtle. Try comparing left and right sides carefully. Look for differences in how the ball sinks in, not just tenderness. If you genuinely cannot find any difference, your tennis elbow may have a different cause, and you should consult a physiotherapist.
Do I need to see a physiotherapist for this?
These exercises are safe to try at home. However, if your tennis elbow persists, is severe, or if you are unsure about your diagnosis, you should consult a physiotherapist. A thorough assessment can identify exactly which spinal segments are involved and provide a tailored treatment plan.
If you have been struggling with tennis elbow that keeps coming back no matter what you do, I encourage you to try this simple test. Your elbow pain may not be an elbow problem at all.
The perspective I want anyone with tennis elbow to have is this: your symptoms are a consequence of something else. The local tendonopathy or nerve irritation is very real, but it has been set up by hidden neck dysfunction. Address your neck, address your daily postures, and you may find that your elbow finally stops hurting.
