How long does it take for a hematoma to disappear on my forearm? it's been two weeks so far?

Haematoma: A haematoma is a fluid collection of blood, as distinct from simple bruising. A bruise usually clears within about three weeks, but a heamatoma can take longer and the time is influenced by how large it is. Because of this i suppose there is no way to give a precise answer, but I am not surprised that it is still there after only two weeks.
