I've been experiencing chronic pounding headaches everyday for the past week. sometimes twice a day. could this be something serious?

It could be...: Having a headache go one for as long as a week is something that needs to be taken seriously and evaluated. Pounding suggests throbbing, often associated with blood vessel pulsating. It could be muscular contraction/tension headache, migraine, or even something more serious so you need a thorough evaluation and appropriate diagnostic tests. See your doctor ASAP. Good wishes:)

Headackes: Migraine: 1-6 days/month, in the morning Tension: 1-7/d/w/tightness-pressure Medication: Deep, following drug intake Sinuses: Tension/pressure/most of the day Cluster: Sharp, 1-4/d, 3-8/w/any time of the day You most probably have tension headaches, you should see a neurologist for confirmation and medication

Possibly;c/wMigraine: (=vascular) headaches: which ↓ ability to function yet are rarely a threat to survival/physical health. Yet can be clue to more serious additional issues: tumor, aneurysm, intracranial bleed, etc. Though infrequent, CT & MRI (better) brain scans are often done looking for such infrequent yet life threatening issues. Best seek assistance worthy of your trust & study my answers, some about migraine.

Yes, it could: You should see a clinician very soon. If you can have your blood pressure checked, at a pharmacy for example, you should do that immediately.
