your child have had a spontaneous rupture of the eardrum -- nature's way of dealing with the pressure and/or infection. some ruptures are tiny and located along the margin of the eardrum - difficult to see; and some are large and quite obvious. either way a ruptured eardrum will bleed and nearly all of them will completely heal in a few weeks.
is it normal for bleeding to occur with bilateral acute otitis media? . my child ear was bleeding for three day before the doctor told me it was bilateral acute otitis media. she did not say her ear was hurting at all.
