Did not sleep much last night and am very tired today, now have a headache with a pulsating feeling in both temples? could that be from lack of sleep?

Or hangover? Hi

Did you consume extra coffee to combat drowsiness? Pulsating sensation in both temples can be caused by increased heart rate and/or blood pressure. Anxiety,stress,heavier caffeine intake can cause these symptoms. If sleep deprivation causes stress the next day, prominent bitemporal pulsations could occur. In your case, I predict that the symptoms will resolve with relaxation.

You may be under a lot of anxiety or stress of some incident that happened that day or of a future problem you are aware of. Are you on medications that you forgot to take?
