 [ 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 ] medications can explain the side pain however i saw a similar case with as much delusions like your mother he was on antidepressant and antihistaminics however it turns out he just had hyperthyroidism which caused all the symptomsgood luck
