Why Migraine Symptoms Are Frequently Misread
Migraine is a very common condition affecting about 1 billion people around the world. However, it still remains immensely underdiagnosed. This is partially because people still think of it as a simple headache. In reality, migraine is a neurological disorder that unfolds across up to four phases: prodrome, aura, headache, and postdrome. Each phase generates its own symptoms, many unrelated to head pain, which are routinely dismissed or attributed to other causes.
Ignored Prodrome Symptoms (Up to 48 Hours Before the Headache)
The prodrome phase can begin one to two days before head pain and is characterized by subtle neurological and physiological changes. These are among the most commonly overlooked:
Neck Pain and Stiffness
Neck pain affects up to 75% of migraine patients and frequently precedes the headache in the prodrome phase. Many patients are treated for cervical or musculoskeletal problems for years before migraine is identified. Neck pain is not a trigger; it is a symptom of the attack itself.
Mood Changes
Mood changes like irritability, anxiety, or feeling low may be experienced before a headache in some patients. They may also experience euphoria or a sudden surge of energy. This is mistakenly attributed to stress and hormones and is not caused by the migraine headache.
Food Cravings and Appetite Changes
Food cravings, particularly those for sweets or carbohydrates, are considered prodrome symptoms rather than migraine triggers. The brain changes associated with a migraine cause the craving, and the food consumed does not initiate the migraine. The craving indicates that the migraine is already underway.
Increased Urination and Fluid Retention
Frequent urination, fluid retention, and altered thirst are autonomic prodrome symptoms almost never linked to migraine by patients or clinicians. They are often investigated for kidney or hormonal causes instead.
Yawning Repeatedly
Excessive yawning unrelated to tiredness is linked to dopamine dysregulation in the migraine prodrome. Patients who recognize it can use it as an early warning to take abortive medication before the headache develops.
Overlooked Symptoms During the Attack Phase
Brain Fog and Cognitive Difficulty
The brain fog, inability to concentrate, slowness of thought, and word-finding difficulty, which often accompany and follow a migraine, are commonly ascribed to lack of sleep or fatigue rather than migraine itself.
Body Chills and Temperature Changes
Chills, shivering, or sweating during a migraine indicate a hypothalamic disturbance. The hypothalamus, which causes the migraine, is also responsible for controlling body temperature. This symptom is generally associated with illness rather than migraine.
Phantom Smells (Phantosmia)
There have been reports of phantom smells, which may come in the form of a burning smell, smoke, or a metallic smell. Phantom smells have been reported by some migraine patients as a migraine aura. Phantom smells are generally associated with migraine aura; however, aura is generally associated with visual manifestations. Olfactory hallucinations have never been associated with migraine; therefore, phantom smells have been misdiagnosed as a neurological or sinus disorder.
Nasal Congestion and Runny Nose
Migraine causes the trigeminal nerve to become active, which results in symptoms of sinus headaches. Nasal congestion and eye watering have been reported by some migraine patients. This symptom mimics sinus headaches; however, research has shown that 90% of self-diagnosed sinus headaches are, in fact, migraine headaches.
Allodynia or Pain From Ordinary Touch
Allodynia is a migraine symptom that causes pain from harmless stimuli. This harmless stimulus may come in the form of touching hair, wearing glasses, or skin contact. This migraine symptom affects 60% of migraine patients.
Silent Migraine or Migraine Without the Headache
Silent migraine (acephalgic migraine) is a complete migraine attack with prodrome, aura, nausea, and sensory changes in which the headache phase is absent or minimal. It is common in older adults and is frequently misattributed to TIAs, vestibular disorders, or anxiety, often going undiagnosed for years.
Postdrome: The Ignored “Migraine Hangover”
Up to 80% of patients experience the postdrome phase for 24 to 48 hours after head pain resolves. Symptoms of fatigue, cognitive difficulty, lingering light sensitivity, and emotional flatness are routinely dismissed as unrelated. Recognizing the postdrome as part of the attack is important when assessing the true disability burden of migraine.
Why Recognizing These Symptoms Matters
Early recognition of the prodrome allows for prompt treatment. Triptans and gepants are most effective during the pre-peak pain period. Knowledge of all migraine symptoms helps avoid investigations for sinus problems, neck disease, and cardiovascular disease. If the pattern of recurring symptoms is recognized, it is advisable to get tests done to confirm the diagnosis of migraine..
Conclusion
Migraine is a neurological disorder that involves the entire body, including neck pain, mood changes, cravings, olfactory hallucinations, brain fogginess, sinus pressure, and allodynia, but the vast majority of migraine patients do not receive recognition of these aspects of migraine until many years into the disease.
Understanding your total symptom pattern during all four phases of migraine is one of the most important steps in proper diagnosis and treatment of migraine headaches.
