He also took Tylenol because of the pain. Advil 200mg strength, had taken seven or eight since, but he only took one at the time. It helped a little but did not cure. He took Tylenol and did not see much difference and thought to switch to Advil for pain. The event did not result in emergency room or physician office visit.
