Chronic Tension Type Headache
Chronic Tension-Type Headache is classified as a mild-moderate headache, that is felt on both sides of the head. It is often described as feeling like a tightening or pressing around the head, as opposed to the pulsating pain that is commonly associated with migraine.
New Daily Persistent Headache
New Daily Persistent Headache is similar to Chronic Daily Tension-Type Headaches, however, they occur in people that have had no prior history of headaches.
Generally, the headache will become constant, or near constant, within three days of the onset of the first headache. Similarly, to Chronic Daily Tension-Type Headaches, these headaches are often described as a tightening and pressing sensation, and not a pulsating pain.
Chronic Migraine usually is a progression of episodic migraine, that worsens over time to become more persistent. These migraines may have gone untreated, or may have progressed naturally over time. Migraine pain is usually experienced on one side of the head, but may switch sides during an attack or appear on a different side of the head between different attacks. The pain is usually described as a throbbing and pulsating pain that is moderate-severe in nature
Hemicrania Continua typically affects one side of the head but will be side-locked and not switch sides.
People who experience these headaches will have moderate pain throughout the whole day, with more severe spikes intermittently. It is also possible for people to experience other symptoms with Hemicrania Continua, such as; swollen or droopy eyelids, eye redness, blocked or runny nose and watery eyes.
Some symptoms associated with migraines can occur, such as nausea and sensitivity to light, sound and smell
