What Causes Blood Blisters?

Accidents That Pinch The Skin

Accidents that pinch the skin have a high chance of causing individuals to develop a blood blister. If the skin is pinched and not broken, it's likely blood will pool up into the blister created from the accident. These accidents can include everything from getting skin pinched in a hinge to having a door close on a finger or toe. Once an individual has suffered from such an accident, they'll likely experience a substantial amount of pain compared to some of the other causes of blood blisters. This pain should dissipate in a few hours. If it doesn't, patients might want to visit a doctor to make sure the area is healing properly and an infection doesn't develop. Some of the signs indicating a blood blister is getting worse include spreading redness, severe amounts of pain, and the location of the blister making it difficult to use one's hands or walk.
