Top Five Astonishing Facts about Blood Blisters You Absolutely Need to Know

Underlying Medical Conditions and Blood Blisters

While the majority of blood blisters occur due to friction or trauma, they can also serve as an indicator for certain medical conditions. Diseases such as bullous pemphigoid, a rare skin disease that is commonly seen in older individuals, or thrombocytopenia, a deficiency of platelets in the blood causing bleeding into the tissues, may result in their appearance. If blood blisters frequently show up without clear causes or stay longer than two weeks, a medical evaluation is highly encouraged.
