Muscle knots: what they actually are and what helps
Almost everyone has felt a muscle knot: a tender, tight spot in the neck, across the top of the shoulders, beside the shoulder blade or in the lower back that aches when you press it. They're one of the most common things people come in about, so it's worth knowing what's actually going on.
What is a muscle knot?
The popular explanation is that a knot is a small, contracted patch of muscle, often called a trigger point, that refers pain elsewhere. The honest answer is that the research doesn't fully support that picture. A systematic review found that clinicians can't reliably agree on where trigger points are through physical examination (Lucas et al., Clinical Journal of Pain, 2009), and a critical review in Rheumatology argued that the theory that trigger points cause pain doesn't stand up, while agreeing that the tender spots and the pain people feel are real and need a better explanation (Quintner et al., Rheumatology, 2015).
A more useful way to think about it: tender, tight areas are sensitive muscle and nerve tissue, often a sign that an area is overloaded, under-recovered, or guarding something else that's irritated nearby.
What causes muscle knots?
Common triggers are sustained positions such as long hours at a desk or driving, sudden increases in training, repetitive work, poor sleep, and stress. Knots often appear around a joint or area that's stiff or irritated, which is why treating only the knot rarely solves the problem for long.
What helps muscle knots?
Short-term relief often comes from pressure (a massage ball or your own hands), heat, and gentle movement. Dry needling has evidence for short-term pain relief: a meta-analysis found it reduced pain compared with no treatment or sham needling over up to 12 weeks, though the quality of evidence ranged from very low to moderate and long-term benefits weren't shown (Gattie et al., JOSPT, 2017).
That's why at RISE we use hands-on treatment and dry needling as part of a plan rather than on their own. We look for what's overloading the area, whether that's your desk set-up, training load, a stiff joint or a pinched nerve, and pair treatment with strength work so the same knot doesn't keep coming back.
Why do I always get knots in my shoulders?
The upper trapezius, the muscle running from your neck to the top of your shoulder, is one of the most common places for knots. It works whenever you hold your arms in front of you, look down at a screen, carry bags, or tense up under stress. Long desk days, heavy upper-body training, poor sleep and stress all tend to make it more sensitive.
Do massage guns and foam rollers help muscle knots?
They can help in the short term. Like hands-on treatment, they seem to work mainly by reducing sensitivity in the area, making it feel easier to move. There's nothing wrong with using them if they feel good. They're most useful as a way to feel better before or after activity rather than a fix for why the area keeps getting sore.
Can you break up a muscle knot?
Not in the way people often describe. Pressure, massage and needling don't physically break anything apart. The change you feel, a knot softening or becoming less tender, is most likely your nervous system reducing the sensitivity and tension in that area. That's still helpful, but it explains why knots come back if the reasons behind them aren't addressed.
What about a knot in my lower back?
Tender, tight spots beside the lower spine or in the buttock are common with back pain, and often reflect muscles guarding an irritated joint or disc. Treating only the tight spot tends to give short-lived relief. It's usually more useful to work out what's being protected, and build strength and movement in the area.
How do I stop muscle knots coming back?
Look at the load on the area. Break up long periods at a desk, set up your screen and workstation well, build strength in the muscles that keep getting sore, and increase training gradually rather than in big jumps. Sleep and stress management matter more than most people expect. If knots keep coming back despite these changes, an assessment can find what the area is guarding or compensating for.
When should a muscle knot be checked?
See someone if the pain isn't settling over a couple of weeks, keeps returning, spreads down your arm or leg with pins and needles or numbness, or comes with weakness. See a doctor promptly for a hard lump that doesn't go away or is growing, or pain with fever or feeling unwell.
If your knot is between your shoulder blades, see our post on pain between the shoulder blades. Book an assessment at our Berwick clinic. A 60-minute initial consultation is $149, with no referral needed and HICAPS on-site.
