Finger barbs are caused by dry, abrasive skin on the hand. A barb is a flesh splinter on the nail that is necrotic in a small piece, free from the rest of the skin on the hand, hanging from the skin on the side or root of the nail. When a patient has a long barb on the finger, it is usually caused by too dry skin, a lot of localized friction, and cracks in the cuticle. When there is a barb on the hand, don’t pull it out in a hurry because the barb is attached to the muscle. When you tear the barb with your hand or with other tools, not only will you feel pain, but you will also injure the surrounding skin, leading to bleeding and causing a hand infection. The proper way to deal with a barb is to soak the hand with the barb in water, wait for the nail and the surrounding skin to become soft, and then use small scissors to cut it off. It is recommended that when patients have barbs on their fingers, they should treat them properly to avoid hand infections and apply more hand cream to protect them in their daily lives.
