R51: Headache

Headache, classified under ICD-10 code R51, is a common pain condition that affects individuals of all ages. It is characterised by discomfort or pain in any region of the head, and it can vary greatly in terms of frequency, intensity, and duration. Headaches may be isolated occurrences, or they may be recurrent, signifying a chronic condition. They can be broadly divided into primary headaches, which are conditions in themselves, and secondary headaches, which are symptoms of other underlying health disorders. Common forms include tension headaches, migraine, and cluster headaches. Various triggers can lead to headaches - stress, certain types of food, lack of sleep, noise, and prolonged screen time are some examples. It's important to note that while common, persistent or severe headaches may be an indication of a more serious underlying condition and should not be ignored.
