You can usually find them with your fingertips — those small, tender, rope-like spots buried in the muscles of your upper traps, your lower back, or the side of your hip. You press, and they push back. You stretch, and they refuse to soften. Sometimes they radiate a dull ache far from where you are pressing, leaving you wondering why your shoulder hurts when the source of the trouble seems to be somewhere else entirely. These stubborn pockets of restricted tissue are commonly called muscle knots, and they are one of the most frequent — and most frustrating — reasons patients walk into our office.
Muscle knots feel deceptively simple to fix. Roll them out, press them harder, stretch them more — surely something will give. But anyone who has lived with a recurring knot in the shoulder or low back knows the truth: most of these tight spots simply do not respond to general stretching or self-massage in the long term. The reason has less to do with the muscle itself and more to do with the layers of connective tissue surrounding it. If you have already read about how stubborn restrictions interact with muscle tightness when returning to exercise, this article picks up where that one left off and focuses specifically on what to do when a knot will not let go.
