Our daughter was diagnosed with an ear infection on Thursday. Today, Sunday, she is complain ing of intermitent knee pain, ankle pain, and back pain. When I took a look at her back I noticed a small bruise (the size of a nickel), an hour later, I noticed a large swollen area around the small bruise, no additional bruising, just swelling, a little larger than a softball in diameter. What is happening with her? She is not taking any oral medication, just drops for her ear.
