Quick Answer
Why 15 or more headache days per month prompts a different assessment approach.
Medically reviewed by Dr. Jitendra Prasad Yadav • NMC 8029 • Kathmandu Neurology Clinic & Cognitive Center
Chronic headache is defined as headache on 15 or more days per month for more than three months. The definition is not merely semantic; it marks a threshold where contributors often overlap —— for example, underlying migraine, tension-type features, sleep and mood factors, and frequency of acute medication use.
A comprehensive review includes a headache calendar, medication history including over-the-counter agents and caffeine, and assessment for red flags that warrant urgent care. The goal is not to imply a single cause, but to identify modifiable contributors and to plan follow-up.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for chronic headache.
Evidence suggests that high-frequency use of acute medications can perpetuate headache frequency. Any adjustment of medication should be done under medical supervision.
If you experience daily headache or need pain relief most days, arrange an evaluation rather than increasing self-medication. Education about expectations and follow-up is a central part of care.

Stress does not cause migraine alone but lowers threshold and increases frequency, especially with irregular sleep and frequent analgesic use.
