Hi, my daughter got a concussion on Thursday. We took her to the ER and said they weren't concerned about a bleed so they didn't order a CT scan. She has had some more problems since then. Severe ear throbbing lasting for about a minute each time, vertigo when standing up to the point where she almost falls over, her headache has been completely constant since Thursday ad hasn't gotten any better, shakiness, extreme fatigue all the time, balance problems. Should we be concerned or is this normal?
