Tension headache: You should see a doctor right away if your headache quickly becomes severe, have fever or stiff neck, have seizure or pass out, or if it began right after you exercised or had a minor injury If not, then you may be suffering from something like tension headache or migraine, and your doctor should be able to help you with that.
