FWIW, I have been using generic Excedrin for years. I get chronic sinus headaches & this works for me. Has Tylonol, aspirin & caffeine in each tablet. Generic is way cheaper than brand name. You can also use "migraine" version of this med (which has the exact same amount as regular) & it works. This is OTC (Over The Counter) med, so you don't need a prescription to buy it. I have noticed the stores ran out of it quick when all this started, I found some at Walmart, Kroger (Frys in AZ) & even Dollar Tree. My headaches are nothing like Randy went thru, just a dull ache. Whenever I fly, I always take this stuff before we land, cuz as plane descends, pressure builds up in sinus. Went thru that once before I realized what was going on.
