Learn to distinguish various types of serious headaches
Headaches are annoying and painful conditions that can occur anywhere and at any time. Generally they are not grave and occur from stress, sinus, and tension. It becomes a problem when you have to separate between dangerous and non-dangerous headaches which are sporadic, but require immediate attention.
A headache that is severe, insistent or linked with other symptoms such as vomiting is a cautionary signal to a dangerous problem. Before you ignore a serious, urgent headache you should know when to see a doctor.
1 Thunderclap headaches
Similar to their names, thunderclap headaches cause pain all of a sudden and these severe headaches peaks within 60 seconds and can start declining after an hour. Some thunderclap headaches, however, can last for more than a week.
Thunderclap headaches are often a warning sign of possibly life-threatening situations, usually linked to bleeding in and around the brain. Therefore it’s extremely vital to seek emergency medical attention if you experience a thunderclap headache.
2 Headache after an injury
If and when you develop a headache after having a head injury you need medical attention immediately. This is called a post traumatic headache and it might indicate that you are having a concussion so you need to consult a doctor. Even an unassuming small injury to the head can cause bleeding in the brain resulting in skull pressure or headache.
Though headache that immediately follows a head injury commonly clears after minutes or days, but sometimes such headaches may persevere for months or rarely years. Headaches may follow a moderate or severe injury to the brain such as a concussion or laceration.
Immediately seek medical attention of the headaches continue for a long time and become gradually intense.
