osteoarthritis
"Years ago I had terrible low back pain. MD suggested Mobic which worked great for several years. About 4-5 years ago I developed atrial fibrillation. My cardiologist told me to definitely get off the Mobic because a side effect is bleeding, so this would worsen the bleeding because one side effect of Xarelto (a blood thinner) is to thin my blood to avoid strokes.  I just read on another site that Mobic can cause AFib. There is no way to know if the Mobic caused the AFib or it developed independently. I suspect the Mobic brought on the AFib, although I have no proof of that. I have been in excellent health. The 1-10 rating scale used above should not be used, because in my case the Mobic was very helpful but probably caused major side effect"
