Most people will have experienced a blister on the back of their heels when getting used to a new pair of shoes. Blisters are clear, fluid-filled sacs that form on the skin as the result of friction. When a blister becomes filled with blood and turns black, purple or dark red, this is known as a blood blister.

Blood blisters, medically known as bullae, are just like normal blisters but filled with blood.
Dr Lee explained: “Blisters and blood blisters are most often caused by pressure or friction to the area.
“They often appear quite suddenly, for example, you may get them on your hands after using DIY tools, or gardening.
“They often occur in hot, sweaty places, or overlying a joint. They may also occur if the skin is pinched.”Insurance Loans Mortgage Attorney Credit Lawyer

“This also applies if the blood blisters are near your eyes or eyelids, or in places where there has been no apparent friction.
“If you get blisters or ulcers on your genitalia, you should see urgent help at the Sexual Health Clinic.”
