The persistent headache

According to the Mayo Clinic, a headache that persists longer than 3 days should be considered a chronic headache. While many people can go many days treating a headache with over-the-counter pain killers, even the directions of use on the pain killers suggest a doctor’s visit after over 3 days of use because a headache that persists over 3 days is likely a symptom of something that cannot simply be treated by pain killers.

Blinding headache

Severe headaches and migraines can cause flashes or temporary blindness, seeing spots or blurry vision. WebMD describes these as ocular migraines, which are rare and can be part of a serious medical problem affecting the nerves or areas in the brain.

While there could also be some comparatively benign reasons for blinding headaches, these can be diagnosed only by a medical professional while ruling out more serious illness.

Headache after a head injury

Concussions and other similar head injuries are usually accompanied by other symptoms like dizziness, nausea and sometimes ringing in the ears. According to a report produced by the TBI Model Systems in collaboration with the Model Systems Knowledge Translation Center, head injuries that cause mild to severe brain injury often first manifest as a headache.
