I am a 54 year old female who has been on warfarin since feb 2010- I am having extreme pain in my?

I don't think this is a side effect of Warfarin. Do you take any other meds? You can go Drugs A to Z at the top of the page & click on it & then click on W it lists the drug warfarin. Just click on it & it will give you all the info about it side efffects & all. If you are taking ny other meds or have other conditions you will see it referenced there. Otherwise, I would see your doctor about the muscle/joint problems you are having. Just my thoughts...

Do u have any bruising on your body? I was on warfarin also fur awhile and I developed bruising all over to the point i couldn't lay on the bed without pain. It was also painful to be touched. I found out I was bleeding inside and had to be hospitalized and given vitamin k to stop the bleeding. Eventually they took me off warfarin because that couldn't control the INR. I am on Xarelto now which is supposed to be safer the only thing is from what I understand if u do start bleeding they don't have the drugs to stop the bleeding as easy so it can be dangerous also. My daughter works in the cath lab and would rather I be on Eliquis but can't afford it so have to take my chances with Xarelto. Just be careful with with those drugs and if u notice any bruising that's unusual u need to let ur doctor know as soon as possible so it can be taken care of. Good luck and I hope this helps.
