Understanding Trigger Points
If you’ve ever pressed on a tight spot in your shoulder and felt it ache far more than you expected, you’ve met a trigger point. They’re one of the most common things I find when patients come in, and one of the least understood.
Most people call them “knots.” They’re small, but they can cause a surprising amount of trouble, sometimes in places that seem to have nothing to do with the muscle itself.
What Is a Trigger Point?
A trigger point is a small area of muscle that has tightened and won’t fully relax. A healthy muscle contracts when you use it and lets go when you’re done. With a trigger point, part of the muscle stays switched on.
Over time, that spot becomes irritated, tender and stiff. You can often feel it as a firm band or small bump under your fingers. Pressing on it usually hurts more than you’d expect for something so small.
Trigger points show up most often in muscles that work hard all day: the neck, shoulders, upper back, low back and hips.
Why Pain Can Show Up Somewhere Else
A trigger point doesn’t always hurt where it is. It can send pain, aching or tingling to another part of the body. This is called referred pain.
For example, a trigger point in the arm can cause tingling in the hand. A patient might be sure something is wrong with their hand, when the real source is a muscle higher up.
That’s why I don’t just treat the spot that hurts. As an osteopathic physician, I look at how the whole body is connected and try to find where the pain is actually coming from.
What Causes Trigger Points?
Trigger points usually build up from everyday habits rather than one big injury. The most common causes are:
Overuse. Repeating the same motion again and again, like typing, lifting, or carrying a child on one hip, keeps the same muscles working without enough recovery.
Dehydration. Muscles need water to contract, relax and repair. When you’re low on fluids, they’re more likely to tighten up and stay that way.
Stress. Many of us carry tension in the neck and shoulders without noticing. Over weeks and months, that tension can settle into trigger points.
Poor sleep. Your body does much of its muscle repair while you rest. Short or restless sleep means less recovery time.
Most of the time it’s a combination. Long workdays at a desk, a stressful season and not enough water can all add up.
How to Tell If You Might Have One
Trigger points often show up as:
A tender spot that hurts more when you press on it
A tight band or small lump in a muscle
Pain that seems to spread or “travel” to another area
Stiffness or a limited range of motion in the affected area
Pain that keeps coming back in the same place
What You Can Do at Home
These everyday habits can help keep trigger points from building up:
Stay hydrated by drinking water steadily throughout the day.
Take movement breaks if you sit or repeat the same task for long periods.
Stretch gently in the areas that tend to tighten, like the neck, shoulders and hips.
Protect your sleep, since that’s when your muscles recover.
Notice your stress, and check in with your shoulders and jaw during the day.
When to Get It Checked
A knot that comes and goes is common. Consider an exam if:
The same spot keeps coming back despite stretching and rest
Pain, tingling or numbness travels into your arm, hand, leg or foot
It’s limiting your work, sleep or daily activities
You’re not sure whether the pain is coming from a muscle or something else
Pain that travels can come from several sources, not just trigger points, so a thorough exam is the best way to know what’s going on.
