 [ Symptoms ] when should i be concerned about a strange bruise  my daughter was spinning in circles 5 days ago she lost her balance and fell to the ground landing on her forearm she says she did not land on any rocks or sticks she developed a very strange bruise it is approximately 3 x 6 long with a hard flesh tonedwhite lump in the middle of it the lump is hard and about 14 in diameter she says that the only thing that hurts is when she pushes on the lump i do not believe it is any sort of bug bite since i could not locate and puncture wounds [ Disease ] she most likely has a hematoma an accumulation or pocket of blood under the skin this is just a guess however since i have no way of seeing or examining your daughter over the internet she would need to see a medical provider for a hands on examination to confirm this assumption in the meantime keep up with the cold compresses
