Trigger points

TrP 1

TrP1

Location. Under jaw, neck

Pain referral. Under jaw, neck, throat

  • Under jaw
  • Neck
  • Throat
  • Ear
TrP 2

TrP2

Location. Anterior belly beneath chin

Pain referral. Submental region and lower incisors

  • Under the chin
  • Lower front teeth
  • Tip of tongue
  • Submental triangle
  • Floor of mouth

Symptoms patients report

Throat pain. Anterior neck and pharyngeal pain from digastric trigger point referral to throat region

Under jaw pain. Submental and submandibular aching from digastric trigger points along jaw underside

Swallowing discomfort. Hyoid elevation dysfunction from digastric trigger points impairing smooth swallowing mechanics

Ear pain. Referred otalgia from posterior belly digastric trigger points near mastoid attachment

Pain under the chin. Anterior digastric trigger points refer to the submental triangle creating under-chin pain

Lower incisor toothache. Referral to the lower anterior teeth mimics dental pathology in the mandibular incisors

Discomfort swallowing. Digastric contraction during swallowing provokes anterior belly trigger points creating dysphagia

Throat pain during swallowing. Floor-of-mouth trigger point referral creates a sensation of throat pain during deglutition

Tongue tip discomfort. Anterior digastric referral extends to the tongue tip via shared mylohyoid nerve territory

Common causes

Swallowing dysfunction. Abnormal swallowing patterns overload digastric muscle during repetitive hyoid elevation cycles

Stress. Psychological tension causes involuntary jaw and throat muscle guarding and sustained contraction

TMJ issues. Temporomandibular dysfunction alters mandibular depression mechanics overloading digastric muscle fibers

Throat clearing. Habitual throat clearing repetitively contracts digastric and suprahyoid muscles excessively

Mouth breathing. Chronic mouth breathing alters mandibular posture overloading the anterior digastric for jaw positioning

Playing wind instruments. Sustained embouchure control demands chronic anterior digastric activation for mandibular stabilization

Prolonged neck flexion (looking down at phone). Forward head posture with neck flexion compresses and overloads the anterior digastric muscle

Post-tonsillectomy compensation. Guarded swallowing after tonsillectomy overloads suprahyoid muscles including the anterior digastric

Chronic throat clearing. Repetitive throat clearing activates the suprahyoid muscles creating cumulative digastric overload

Treatment & self-care

immediate

Finger pressure under the jaw along the digastric

Tilt your head back slightly to expose the underside of the jaw. Using your index and middle fingers, press gently upward into the soft tissue under the chin, starting at the midline and working outward toward the jaw angle on each side. When you find a tender nodule, hold steady gentle pressure for 15-20 seconds until the tenderness begins to ease. Work slowly along the entire length of the jaw underside from chin to ear on both sides.

Duration
2-3 minutes total
Frequency
2 times per day
Expect
Reduced under-chin pain and improved swallowing comfort within 1-2 weeks of consistent treatment
exercise

Chin tuck exercises

Sit or stand with your back straight. Gently draw your chin straight back as if making a double chin — do not tilt your head up or down. Hold the tucked position for 5 seconds, feeling a gentle stretch at the base of the skull and a mild contraction under the chin. Release slowly. Repeat 10-15 times. This exercise strengthens the deep neck flexors and gently stretches the digastric and suprahyoid muscles.

Duration
2-3 minutes per session
Frequency
3-4 times per day
Expect
Improved neck posture and reduced digastric muscle tension within 2-3 weeks
exercise

Gentle mouth opening range of motion

Place the tip of your tongue on the roof of your mouth behind the upper front teeth. Slowly open your mouth as wide as you comfortably can while keeping the tongue on the palate — when the tongue starts to pull away, that is your comfortable limit. Hold the open position for 3 seconds, then slowly close. Repeat 10 times. This exercise gently stretches the digastric while the tongue position prevents excessive opening.

Duration
2-3 minutes per session
Frequency
2-3 times per day
Expect
Improved mouth-opening range and reduced pain with jaw movement within 2 weeks
lifestyle

Soft food transition during flare-ups

During periods of increased under-chin pain or swallowing discomfort, temporarily switch to soft foods that require minimal chewing and easy swallowing — warm soups, smoothies, mashed foods, soft-cooked vegetables, and yogurt. Avoid foods that require forceful biting or prolonged chewing. Take smaller bites and eat slowly. Avoid chewing gum. This reduces the repetitive loading on the digastric muscle during its active recovery period.

Duration
Throughout flare-up periods, typically 5-10 days
Frequency
Every meal during active symptoms
Expect
Reduced mechanical stress on the digastric muscle allowing trigger point irritability to calm down
lifestyle

Posture correction for forward head position

Forward head posture places chronic strain on the digastric and other suprahyoid muscles. Set up your workstation so that your monitor is at eye level and at arm's length distance. Keep your ears aligned over your shoulders when sitting and standing. Use a supportive pillow that maintains neutral cervical alignment during sleep. Set hourly reminders to check your head position throughout the workday and gently correct by drawing the chin back.

Duration
Ongoing throughout the day
Frequency
Continuous awareness with hourly check-ins
Expect
Reduced chronic strain on digastric and suprahyoid muscles, decreased baseline pain levels within 3-4 weeks
professional

Professional evaluation for persistent throat or swallowing symptoms

If pain under the chin, unexplained tooth pain, or swallowing difficulty persists beyond 3-4 weeks of self-care — or if symptoms are new and worsening — seek evaluation from an ENT specialist or dentist to rule out dental pathology, salivary gland issues, or throat conditions. Once serious causes are excluded, a physical therapist experienced in cervical and orofacial conditions can provide targeted manual therapy to the digastric and suprahyoid muscles.

Duration
Initial consultation typically 30-60 minutes
Frequency
As needed based on symptom persistence and severity
Expect
Definitive exclusion of dental or throat pathology and a targeted treatment plan for digastric trigger point management
