Hi, i have a severe headache and high fever during the night. slight cough, body chills as well.

See below: The symptoms you describe are consistent with possible Covid 19 infection, as well as possible influenza virus. A person of your age is at higher risk of more serious outcome. Recommend consult your physician, test for Covid, self-quarantine until test result, supportive treatment with rest, increased fluid intake, acetaminophen for fever or headache. Best wishes!
