Clinically, symptoms of a cold headache can be addressed by visiting a general internal medicine department or the gastroenterology department at the hospital. A headache caused by a cold may be due to fever or inflammation-induced neuralgia. Firstly, it is advised to drink plenty of water and rest. Usually, a hospital visit entails a physical examination, a blood test for routine blood work, and C-reactive protein, along with taking your temperature to determine if there is a bacterial infection and any viral infection symptoms. Based on the test results and individual symptoms, detailed treatment measures should be taken, and adequate hydration and rest can aid in recovery.
