Doc.i have slight headaches for 4 days now.i had my hair wet fr almost an hour 2 days before i had this.can it be cold as i dont hv any other symptoms?

Headache: It's unlikely that your headache is from a cold if you have no other symptoms. There are other potential explanations for your headache, however, which include tension headache or migraine. Try taking Ibuprofen or Tylenol (acetaminophen) (if safe for you) for relief. If it persists or this still concerns you, you should see your doctor for an evaluation, as there are other, more concerning causes. Best wishes.

Safer to be checked: Better to see your Doctor, it may be from what you described , then Advil is a better choice for few days than Tylenol (acetaminophen). But it may be something else as well , hypertension, frontal sinusitis , tension headache. So better have a follow up with your Doctor.
