So…. this is older news, but seemed really relevant these days, especially as I (Dr. Carr) have been suffering from migraines, which I suspect is a side effect of the booster shot for Covid. Now, I don’t recommend that anyone use the Internet to diagnose their problems… unless it’s my website, of course!
Why? Because when you Google a condition, or a symptom, you’re really only getting the best SEO for that condition! There are tens of different headaches out there, as defined by Cephalalgia, the leading and most respected peer-reviewed journal on headaches.
Of course, I’d be lying if I didn’t include the classic “Chiropractic Migraine” page, and say that we are miracle workers with that.
Still, 9 BILLION dollars flippin’ amazing.
