Found out I had another stroke a few weeks ago. I have been taking nsaids on a regular basis (ibuprophen, sodium naproxin, etc.) for arthritis in my foot, knee, back, hand, arm, shoulder, wrist and thumb (meat cutting injuries and arthritis) and I did not know they negated the affects on my blood thinners. So, please tell anyone on blood thinners to take Tylenol[emoji]174[/emoji] Extra Strength (or Acetominophen) ONLY, it will not interfere like nsaids do. The best of health to everyone!
