I have been taking Warfarin since September. I have been having problems with my face. It started out as numbness on the one side of my face. It has turned into being hot,heavy, numb, and my ears are clogged. A sinus infection has been ruled out. I went to a neurologist and she ordered a mri. My CT scan was clear. I didn't know if this could be from Warfarin since everything started about a month and a half after I started taking it. I have been pretty healthy until getting multiple PEs from a knee injury in September.
