My 71-year-old Mother Has Primary Pulmonary Hypertension And Saw Her

My 71-year-old mother has primary pulmonary hypertension and saw her cardiologist on Monday where she had a heart catherization. Today she's experiencing an odd sensation when her right hand touches another body part, as if it's not actually her hand, but someone else's. She says her left hand feels normal except if she touches her right leg. Is this a side-effect of the heart cath?
