The general treatment for a pinched finger with bruising on the nail cap includes local ice compress, gauze bandage, splint fixation, etc. The doctor will decide the treatment according to the patient’s specific situation. 1. Local ice compress: If the extent of nail bruising is small and there is no obvious local swelling and pain, the patient can use local ice compress under the guidance of the doctor to reduce tissue exudation. In addition, after 24 hours, patients can use hot compresses to effectively promote the absorption of nail bruises. 2. Gauze dressing: If the nail bruise is extensive and accompanied by obvious swelling and fluctuating sensation of the nail bed, which indicates that there may be active bleeding under the nail bed, then the doctor will remove the nail under local anesthesia to completely remove the bruise under the nail bed. Afterwards, the doctor will use sterile gauze with pressure bandage to protect the wound. 3. Splinting: If the patient has a fracture of the phalanx, the doctor will first use a finger splint for external immobilization. 4. Medication: Ibuprofen, acetaminophen for pain relief, amoxicillin, cefaclor and other antibiotics to prevent infection. When the finger is pinched resulting in nail cover with bruises, the patient should pay attention to the protection of the wound to avoid secondary injuries, and promptly go to the hospital, under the guidance of a professional doctor for treatment.
