Why do measles hurt so badly?

Measles can cause significant discomfort due to the body's immune response to the virus. This response includes fever, inflammation, and a rash, which can lead to intense itching and pain. Additionally, the infection can cause respiratory symptoms, sore throat, and body aches, all contributing to the overall pain and discomfort experienced by the affected individual. The severity of symptoms can vary, but the combination of these factors often makes measles particularly painful.
