Muscle Knots: What They Are, Causes and How to Get Rid of Them

01What

What is a muscle knot?

Muscle knots are not literally knotted muscles. They are areas where muscle fibres stay contracted and tender, often within a tight band. Many clinicians describe them as myofascial trigger points: spots that are sensitive to pressure and may refer pain to other areas. Ultrasound studies show some differences in these areas, but how they form is still debated. Whatever the exact cause, they respond to the same approaches: reducing overload, improving circulation and restoring normal movement. Hands-on treatment is described in our guide to trigger point therapy.

02Where

Where knots commonly occur

• Upper trapezius: between the neck and shoulder, often linked to desk work and stress.
• Levator scapulae: at the side of the neck, from looking down at phones.
• Rhomboids: between the shoulder blades.
• Lower back muscles: after lifting or long sitting.
• Glutes: in runners and people who sit a lot.
• Calves: in runners and after unaccustomed walking.

03Causes

Causes

• Long periods in one posture, especially at screens.
• Repetitive movements at work or in sport.
• Sudden increases in exercise or new activities.
• Carrying heavy bags on one shoulder.
• Stress and anxiety, which increase muscle tension.
• Poor sleep or awkward sleeping positions.
• Dehydration and low fitness.

04Symptoms

Symptoms

• A tender spot that hurts when pressed.
• A feeling of tightness or a small lump.
• Aching or burning in the area.
• Stiffness and reduced range of motion.
• Pain spreading to other areas, such as headaches from neck knots.
• Symptoms worse with stress or after long periods of sitting.

05Relief

How to get rid of muscle knots

• Move: gentle movement and walking improve circulation; avoid complete rest.
• Heat: a warm shower or heat pack for 15–20 minutes relaxes muscles.
• Self-massage: lean against a tennis ball on the wall and apply gentle pressure for 30–90 seconds.
• Foam rolling: slow rolling over larger muscles.
• Stretching: gentle neck, shoulder and back stretches held for 20–30 seconds.
• Strengthening: build strength in overloaded muscles so they cope better.
• Stress management: breathing exercises, exercise and enough sleep.

06Stretches

Stretches for neck and shoulder knots

• Upper trapezius stretch: tilt the ear toward the shoulder and hold 20–30 seconds each side.
• Levator scapulae stretch: turn the head 45 degrees and look down toward the armpit, 20–30 seconds.
• Shoulder rolls: 10 backward circles.
• Doorway chest stretch, 30 seconds.
• Thread the needle for the upper back.
• Pair stretches with posture changes; see neck muscle strain.

07Massage

Does massage help?

Many people find massage helpful for knots, at least in the short term. Massage increases blood flow, reduces muscle tension and can lower pain sensitivity. Effects tend to wear off unless the causes are addressed. Physical therapists may combine massage with dry needling, exercise and posture advice. Deep pressure should be uncomfortable but tolerable, not severely painful.

08Prevent

Preventing knots

• Take breaks from sitting every 30–45 minutes.
• Set up your workstation so your screen is at eye level.
• Warm up before exercise and increase training gradually.
• Use a backpack rather than a shoulder bag.
• Strength train two to three times a week.
• Stay hydrated and sleep well.

09Cases

Three common situations

• Desk worker with knots in the upper shoulders and headaches: regular breaks, neck stretches, ball release and screen adjustments usually help.
• Runner with tender spots in the calves: foam rolling, calf strengthening and gradual training increases.
• Stressful week with tight shoulders: heat, breathing exercises and gentle movement can ease tension.

10Sleep

Sleep, stress and muscle knots

Many people notice that knots in the neck and shoulders are worse during stressful periods or after poor sleep. Stress activates the nervous system and increases resting muscle tension, particularly in the upper trapezius, and poor sleep lowers the threshold for pain. Breathing exercises, regular physical activity, a consistent sleep routine and a supportive pillow that keeps the neck level can reduce both tension and tenderness. If you clench your teeth or grind at night, the jaw and temple muscles can also develop tender spots; a dentist can advise on a night guard.

11Other

Is it a knot or something else?

• Lipoma: a soft, movable, painless lump of fat under the skin.
• Swollen lymph node: a small, rubbery lump in the neck, armpit or groin, often with infection.
• Cyst: a smooth lump that may become red or tender if infected.
• Muscle strain: sudden pain after a specific movement, sometimes with bruising.
• Fibromyalgia: widespread pain and tenderness with fatigue and poor sleep.
• A lump that is hard, fixed, growing or painless deserves a doctor’s check.

12Summary

Key points to remember

• Muscle knots are tender, tight spots in muscles, common in the neck and upper back.
• Posture, overuse and stress are common causes.
• Movement, heat, self-massage, stretching and strengthening help.
• See a doctor for hard, growing or unusual lumps.
