The headache type changes the treatment question
NHS describes tension headaches as commonly affecting both sides with a pressing or tightening feeling. Migraine often has a different pattern and associated symptoms. Calling every headache a tension headache can lead to the wrong treatment choice. [1]
Migraine findings have a defined scope
NIH describes limited evidence that magnesium may reduce migraine frequency and recommends clinical oversight for that use. These findings do not establish relief of an acute tension headache or prevention of all headache types. [2]
The inspected guidance supports other first steps
NHS discusses suitable pain relief, relaxation, exercise, sleep habits and attention to caffeine for tension headaches. Frequent or severe episodes may need assessment and preventive treatment. Taking painkillers too often can itself contribute to headaches. [1]
Do not escalate magnesium to chase pain relief
The inspected sources do not identify a best magnesium form or a universal dose for tension headaches. High supplemental exposure can cause diarrhea and other adverse effects, with greater toxicity risk when kidney function is impaired. [2]
Use a diary and respond to red flags
Imagine headaches occur during poor sleep and heavy caffeine use. Record timing, symptoms, medicines and possible triggers. A sudden extremely painful headache, new neurological problems or headache with fever and a stiff neck requires emergency assessment rather than a supplement trial. [1][3]
| Evidence or symptom | Implication |
|---|---|
| Migraine-prevention research | Not all headache types |
| Pressing bilateral pattern | May fit tension headache; assess context |
| Frequent analgesic use | Can contribute to headache |
| Sudden severe or neurological symptoms | Emergency assessment |
