Petechiae

Signs and symptoms of thrombocytopenia may include:

  • Easy or excessive bruising
  • Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs
  • Prolonged bleeding from cuts
  • Spontaneous bleeding from your gums or nose
  • Blood in urine or stools
  • Unusually heavy menstrual flows
  • Profuse bleeding during surgery or after dental work

When to see a doctor
Make an appointment with your doctor if you have any signs or symptoms that worry you.

Bleeding that won't stop is a medical emergency. Seek immediate help if you experience bleeding that can't be controlled by usual first-aid techniques, such as applying pressure to the area.
