There are two types of bruises after the toe is crushed. There may be localized bruises and pain in the soft tissues of the toe, or there may be separation of the nail and the nail bed, which leads to rupture and bleeding in the nail bed and thus bruises at the root of the nail. In the case of soft tissue swelling, the swelling will gradually dissipate by applying cold compresses at an early stage, hot compresses at a later stage, physical therapy, or topical ointments to relieve swelling and pain and to activate blood circulation. However, if it is a swelling under the toenail, it usually has to be released before it can disappear. There are two ways: First, a small hole can be drilled in the toenail with a needle, and the blood can be discharged from the hole by itself, but in this case, if you accidentally get wet, sewage can flow into the toenail through the hole, which can easily cause inflammation inside. Second, the nail can be completely removed after local anesthesia in the toe to remove the hematoma inside, which can solve the problem at root.
