Have frequent headaches. i take excedrin often. how can i tell if its a rebound headache or a migraine? throb pain on left temple and head side.

CDH vs rebound HA: The diagnosis must be confirmed by observing that the intensity of the headache significantly lessens after a period of complete abstinence (usually one month) from the medications in question. See a headache specialist for proper diagnosis and treatment options.

Frequency is key: If you’re using Excedrin more than 9 days per month, it’s very likely to be a rebound headache.
