Severe Pain In Ear And Pulse Behind Ear After Getting Hit. Took Advil. What Could This Be?

my 4 year old had an incident at daycare she says she hit a table or hit her head somehow now exactly sure the true story, but has had severe pain and has been non stop holding her right ear. I touched her ear and i felt a fast pulse behind at the bottom of her ear and also that part is feeling hot. I put some ice gave her some advil, what else should i do. She has seen a doctor and her doctor said muscle spasm. Im thinking it may be more than that.?
