Secondary headaches are symptoms of something else happening in the body. Continued secondary headache triggers can lead to chronic headaches. Treating the underlying cause generally helps relieve headaches.
Following are the types of secondary headaches along with the causes of headaches:
Allergies or Sinus Headaches
Headaches may occur as a result of an allergic reaction. The pain from these headaches is often concentrated in the sinus area and the front of the head. Migraines are often misdiagnosed as sinusitis. People with chronic seasonal allergies or
sinusitis are prone to this type of headache.
Hormonal Headache
Women often suffer from headaches related to hormonal fluctuations. Menstrual periods, birth control pills, and pregnancy can all affect estrogen levels and cause headaches. Headaches specifically associated with the menstrual cycle are also known as menstrual migraines. These can occur just before, during, and after menstruation, and during ovulation.
Caffeine Headache
Caffeine affects blood flow to the brain. Frequent migraine sufferers are at risk of triggering headaches due to caffeine consumption. If you are accustomed to exposing your brain to a certain amount of caffeine, a stimulant, on a daily basis, not consuming caffeine can give you headaches. This may be because caffeine alters brain chemistry and withdrawal from caffeine can cause headaches.
Exertion Headache
Exertion headaches occur after a period of strenuous physical activity. Weightlifting, running, and sex are common causes of headaches. These activities are thought to lead to increased blood flow to the skull, which can cause throbbing headaches on both sides of the head. An exertion headache does not last long. This type of headache usually subsides within minutes to hours.
Hypertension Headache
High blood pressure can also be among the causes of headaches. This type of headache signals an emergency. It occurs when blood pressure becomes dangerously high. Hypertension headaches usually occur on both sides of the head and usually get worse with activity. If you have high BP and if you experience the following symptoms with a headache, you should see the doctor immediately:
- Changes In Vision
- Numbness Or Tingling
- Nosebleed
- Chest Pain
- Difficulty Breathing
Rebound Headache
A rebound headache, also known as a medication overuse headache, can feel like a dull tension-type headache or more intense, like a migraine. If you frequently use over-the-counter (OTC) pain relievers, you may be prone to this type of headache. Taking over-the-counter medications for more than 15 days in a month increases your chances of developing rebound headaches. These OTC drugs that cause this type of headache include:
- Paracetamol
- Ibuprofen
- Aspirin
- Naproxen
It is also common with drugs that contain caffeine.
Post-traumatic Headache
Post-traumatic headaches can occur after any type of head injury. These headaches feel like migraines or tension headaches. They usually last up to 6-12 months after the injury occurs. They can also become chronic.
Spinal Headache
Spinal headache is the result of decreased cerebrospinal fluid pressure after a spinal tap. For this reason, it is also called a post-dural puncture headache. You may experience headaches in the following parts:
- Forehead
- Temples
- Upper Neck
- Back Of The Head
- Studies estimate that spinal headaches follow a spinal tap 10-40% of the time. Onset usually begins within a few days but can begin months later.
Other symptoms of spinal headaches are:
- Nausea
- Neck Pain
- Dizziness
- Change In Vision
- Tinnitus
- Hearing Loss
- Radiating Pain In Arm
In most cases, the episodic headache disappears within 48 hours. However, you should seek medical attention if the headache lasts more than 2 days or increases in intensity.
If someone has headaches that last for more than 15 days in a month for 3 months, he/she may have chronic headaches. And in such cases, even if over-the-counter medications help control the pain, one should definitely see a doctor. Headaches can be symptoms of more serious health conditions, some of which require treatment beyond OTC medications and home remedies.
