Brief Answer:
Signs of bleeding,should change dosage of Warfarin...

Detailed Answer:
Hi my dear,

Warfarin is a blood thinning drug. Its use increases the chances for bleeding.

Bruises that are appearing on your arms and rib cage lately are indicative for possible bleeding.

I advise to:
- run INR and prothrombin time testing
- consult with your doctor to change the dosage of warfarin.

Hope it was of help!
