Blood clots, a low platelet count, and damaged red blood cells cause the signs and symptoms of thrombotic thrombocytopenic purpura (TTP). The signs and symptoms include: Purplish bruises on the skin or mucous membranes (such as in the mouth). These bruises, called purpura, are caused by bleeding under the skin. Pinpoint-sized red or purple dots on the skin. These dots, called petechiae, often are found in groups and may look like a rash. Bleeding under the skin causes petechiae. Paleness or jaundice (a yellowish color of the skin or whites of the eyes). Fatigue (feeling very tired and weak). Fever. A fast heart rate or shortness of breath. Headache, speech changes, confusion, coma, stroke, or seizure. A low amount of urine, or protein or blood in the urine. If youve had TTP and have any of these signs or symptoms, you may be having a relapse (flareup). Ask your doctor when to call him or her or seek emergency care.
