Yesterday I had a very severe headache, and today I have a headache along with neck pain, a cold, and a fever. What medicine should I take?
Viral infections usually cause severe headache, neck pain, fever, and a cold, but in some cases, they can indicate a more serious condition that needs urgent medical attention. You should see a doctor as soon as possible to ensure it is not something serious. Meanwhile, you can rest, drink plenty of fluids, and take paracetamol to relieve fever and pain, but avoid any other medications until a healthcare professional advises you.
