Maybe it's your body trying to have a 'hold my beer' moment after hearing our tales of woe.That sucks, I was taking 3200mg of ibuprofen a day. Of course I had to go and speak up about being good, and today my back is killing me. Only happened twice since surgery and today is one of the times. LOL
Seriously though,, sorry to hear about the bad day/downturn, hope it gets better really soon and was just as simple as weather/air pressure messing with things.
