The fastest way to reduce the swelling of a big bump on the head

A large head bump may be a subcutaneous hematoma, as well as a subcapsular tendon membrane hematoma or a subperiosteal hematoma, which are treated differently depending on the situation.

2. subcapsular tendon membrane hematoma: subcapsular tendon membrane hematoma is more serious, if the hematoma is small, it can be bandaged with pressure and wait for its self-absorption, if the hematoma is large, it can be punctured and aspirated and then bandaged with pressure.
3. Subperiosteal hematoma: The treatment of subperiosteal hematoma is similar to that of capitellar subperiosteal hematoma, but one should be alert to whether it is accompanied by skull fracture, and if there is skull fracture, pressure bandage should not be applied to avoid causing epidural hematoma.
