Headache at the end of your period: what to know

Hormone levels shift around menstruation, and some people notice a migraine or tension-type headache as bleeding tapers. Low fluid intake, lighter eating, poor sleep, emotional strain, heat exposure or caffeine changes can add to the discomfort. A throbbing pain, nausea, or sensitivity to light and sound fits a migraine pattern; pressure around the head or neck can fit a tension pattern. Nasal congestion, fever or facial pressure may point toward an illness such as Allergic Rhinitis, Chronic Sinusitis or a Common Cold. Headache alone cannot identify its cause.

Drink fluids regularly, eat a balanced meal, rest in a quiet dim room if light worsens the pain, and use a cool or warm compress according to what feels soothing. Keep caffeine and sleep times steady rather than making abrupt changes. Record the start and end of the headache, bleeding days, pain location, associated symptoms, medicines used and possible triggers. A pharmacist or clinician can help you choose a suitable pain reliever, especially if you are pregnant, have another medical condition or take regular medicines.

Seek urgent medical help for a sudden severe headache, new weakness or numbness, trouble speaking, fainting, confusion, a stiff neck with fever, repeated vomiting, vision loss, or a headache after a head injury. Arrange a clinical review if this pattern keeps returning, becomes harder to control, changes from your usual headaches, or occurs with heavy bleeding, marked tiredness or dizziness. Fever with severe headache after travel or mosquito exposure also deserves prompt assessment; Dengue Fever is one condition a clinician may consider.

Could this pattern be menstrual migraine or tension-type headache? Should I keep a headache and period diary? Which pain medicines are appropriate for me, and when should I avoid them? Do my other symptoms suggest dehydration, an infection or another problem?
