Understanding Headaches: Causes, Types, and Relief Strategies

Headaches are the most common pain disorder worldwide, affecting roughly 66% of the global population. The International Headache Society classifies headaches into several categories:
  • Tension-type headaches
  • Cervicogenic headaches
  • Migraine and cluster headaches
  • Secondary headaches resulting from underlying conditions (e.g., fever, infection, sinus issues, or tumors)
  • Cranial neuralgias, facial pain, and other headache syndromes
    
    
    

Tension-Type Headaches

Tension-type headaches are the most common form of headache in adults, with studies suggesting that 30–80% of U.S. adults experience them. These headaches often result from stress, poor posture, fatigue, jaw or neck pain, or dysfunctional breathing patterns.
People often describe the pain as a dull ache or tight, band-like pressure around the head — particularly at the temples, forehead, or the back of the neck. The discomfort can last anywhere from 30 minutes to several days and usually affects both sides of the head, although it may occasionally occur on one side.
Anatomically, this pain occurs because the neck muscles attach to the cervical spine and skull. When these muscles tighten or spasm, they can “tug” on the skull and create tension that radiates into different regions of the head. Depending on which muscles are involved, pain may be felt at the base of the skull, across the forehead, or above the eyes.




Common Muscles That Contribute to Tension Headaches

  • Upper Trapezius
  • Sternocleidomastoid
  • Levator Scapulae
  • Suboccipitals
  • Scalenes
These muscles, when tight or overused, can refer pain into the head and mimic classic headache symptoms.


Managing Tension Headaches

Over-the-counter medications such as Tylenol, Advil, Motrin, or Aleve can help relieve symptoms, but it’s important to consult your doctor before use. Always take the lowest effective dose, as overuse can sometimes lead to rebound headaches — a worsening cycle of pain triggered by frequent medication use.




Cervicogenic Headaches

Unlike tension headaches, cervicogenic headaches stem from dysfunction in the upper three cervical spine segments (facet or zygapophyseal joints). Nerves originating in the cervical spine provide sensory and motor information to the head and neck, and irritation of these nerves can produce referred pain that mimics a headache.




Common Identifiers of Cervicogenic Headaches:

  • Pain primarily on one side of the head (though both sides can be affected)
  • Restricted neck movement or stiffness
  • Pain triggered by neck movement or awkward postures
  • Pain reproduced by pressure at the base of the skull or upper cervical spine
  • Accompanying same-sided neck, shoulder, or arm pain




Treatment and Outlook

Research shows that neck-specific exercises — particularly low-intensity endurance training — and spinal mobilization can be effective both in the short and long term for managing cervicogenic headaches.
It’s also important to note that not all headaches share the same cause. Some result from dehydration, lack of sleep, or underlying medical issues. Identifying the root cause is the first step toward effective relief — and many cases can be managed without heavy reliance on medication.
In some instances, a local anesthetic injection may be required for pain relief, but this is typically reserved for more severe or persistent cases. Physical therapists can play a crucial role in addressing both tension-type and cervicogenic headaches through posture correction, strengthening, and manual therapy. When in doubt, consult a neurologist or primary care physician to help determine the underlying source of your headache.


Treatment Strategies:

1. Posture Correction & Mobility Exercises

These target stiffness and poor alignment — common triggers for both tension-type and cervicogenic headaches.

Chin Tucks

  • How: Sit or stand tall. Gently draw your chin straight back (as if making a double chin), keeping your eyes level.
  • Hold: 5 seconds
  • Reps: 10–15
  • Goal: Strengthen deep neck flexors and counteract forward-head posture.

Upper Trapezius Stretch

  • How: Sit tall. Gently tilt your head to one side (ear toward shoulder). Use your hand to lightly increase the stretch.
  • Hold: 20–30 seconds each side
  • Reps: 2–3 per side
  • Goal: Reduce tightness in the upper trapezius muscles.

Levator Scapulae Stretch

  • How: Sit tall. Turn your head 45° to one side, then look down toward your armpit. Use your hand to apply gentle pressure on the back of your head.
  • Hold: 20–30 seconds each side
  • Reps: 2–3 per side
  • Goal: Decrease neck base and shoulder tension.

Thoracic Extension (on a Foam Roller)

  • How: Lie with a foam roller under your upper back, knees bent. Support your head and gently arch backward over the roller.
  • Hold: 2–3 seconds
  • Reps: 10–12
  • Goal: Improve upper-back mobility and reduce strain on the neck.


2. Neck Strengthening & Endurance Training

These build stability in deep neck muscles that often weaken due to poor posture or prolonged screen time.

Deep Neck Flexor Endurance (Nod Exercise)

  • How: Lie on your back with knees bent. Gently nod your head (“yes” motion) without lifting it off the floor.
  • Hold: 5–10 seconds
  • Reps: 10–12
  • Goal: Strengthen deep cervical flexors — crucial for posture and neck support.

Scapular Retraction (Shoulder Blade Squeeze)

  • How: Sit or stand tall. Gently squeeze your shoulder blades together and down (avoid shrugging).
  • Hold: 5 seconds
  • Reps: 10–15
  • Goal: Strengthen mid-back muscles that support the neck.

Isometric Neck Presses

  • How: Press your head gently into your hand (forward, backward, side to side) without actual movement.
  • Hold: 5 seconds each direction
  • Reps: 5–10 each way
  • Goal: Build neck stability and reduce muscular fatigue.


3. Breathing & Relaxation Techniques

Dysfunctional breathing and stress can amplify headache frequency and intensity.

Diaphragmatic Breathing

  • How: Sit or lie comfortably. Place one hand on your belly and one on your chest. Inhale deeply through your nose so your belly rises, then exhale slowly through your mouth.
  • Duration: 2–5 minutes
  • Goal: Reduce muscle tension and activate relaxation responses.


4. Daily Habit Fixes

Simple lifestyle adjustments can make these exercises even more effective:
  • Take movement breaks every 30–45 minutes during desk work.
  • Keep your monitor at eye level to reduce neck strain.
  • Stay hydrated and get adequate sleep.
  • Consider gentle yoga or Pilates to maintain flexibility and posture control.
