No but,,: A low INR is not a direct cause if pain. It stands for International Normalized Ratio and is the ratio of the patients prothrombin time to a normal prothrombin time value raised to the power of the ISI (international Sensitivity Index) or a ratio of tissue factor to a reference tissue factor. However if it's low it can mean that the blood is clotting more and can lead to thrombosis in patients.
