Hard to know: Any history of bleeding due to platelet or blood clotting problems? This isn't the most typical site for petechiae to spontaneously develop, however, if there is a disease-process at play (autoimmunity against platelets or medication known to affect platelet counts as examples), then it's possible. Your physician is better equipped to comment. Notably, at goal INR, warfarin can cause skin changes
