I looked it up last night. It said nsaids could interfere with blood clotting. I thought that was just aspirin, but apparently not. Better safe than sorry! I love my ibuprofen - so yeah that stuff really does work! I come home from my chiropractor aching all over, pop a couple, take a nap, and wake up feeling like a million bucks.
So now you have time to prepare. Its all good!
