Why does a cold cause headaches? A cold is a viral infection, and the inflammation stimulates the body's temperature regulation center, causing immune-related fever, which leads to complications such as fever, headache, and limb pain. Additionally, a cold can cause symptoms like a runny nose, sneezing, and tearing, which can also pull and cause forehead pain. Therefore, whether the headache is caused by any of these reasons, one can choose non-steroidal anti-inflammatory analgesic medications to relieve the symptoms. At the same time, treatment should also be paired with symptomatic medication and antiviral drugs for a targeted approach.
