my child-age 5- woke up screaming in the middle of the night and told me his ear hurt-the outside part. I figured he had slept on it funny/it got folded while sleeping etc. However, today the upper part is bruised-turning purple. It is the upper part of his ear-nowhere near his head. I am assuming he banged it on the wooden rail of the bed (we use the upper part of a bunkbed as a separate bed -so it has a headboard, footboard and wooden rails all along the sides). He sleeps all over the bed-sideways etc.and moves around a lot in his sleep. He's acted fine all day long. It just seems like a weird place to get a bruise and it wasn't there when I put him to bed. I'm using Arnica cream and Arnica homeopathic pellets. Anything else I should look for? No other bruising anywhere else on him and no other symptoms.....Just curious if I should be worried or do anything else at this point? I assume it will take quite some time to go away just like bruises anywhere else on the body.
