A fall on the head may be a scalp hematoma, which can be helped by ice packs, compression bandages, and puncture suction to reduce swelling. The human scalp has a lot of blood vessels. If a violent blow or fall makes the blood vessels rupture, but there is no obvious break in the scalp, a scalp hematoma will form. For a bump on the head after a fall, after determining that it is a scalp hematoma, ice packs, pressure bandages, and puncture suction can be used to help reduce the swelling. If it is a simple subcutaneous hematoma, the lump is more limited and there is no obvious fluctuating sensation, it usually does not need special treatment, and it can be absorbed by itself after a few days. Ice compresses can help reduce the swelling, make the blood vessels constrict, and reduce the further exudation of fluid. If it is a hematoma under the capitellum, a relatively small hematoma can be bandaged with pressure and wait for its self-absorption; if the mass is relatively large, it can be punctured and aspirated, and then bandaged with pressure. It is recommended to consult the hospital as soon as possible for standardized examination and treatment, and perform head CT examination if necessary.
