<s>[INST] Hi..I was cleaning my 18months old son ear with a cotton swab and to see little blood was there..though I didn t poke too much in and my son didn t even cry..he seems to be ok and doesn t complain anything but I m just worried I have not damage his eardrum or something..please advice what should I do..thank s in advance [/INST] Hi,It seems that while cleaning ear canal with cotton bud there might be having some minor injury in ear canal leading to some some bleeding.There is less likey of injuring ear drum as ear canal is not straight but slight curved and there is no pain.Do not disturb now with cleaning and within 2-3 days it be healed up.Ok and take care. </s>
