My 10 year old athletic daughter was diagnosed with mild concussion 11 days ago from hitting her head. She was dizzy and sleepy for 3 days and then seemed fine after that. We continued to rest her from sports until a week had passed and the Dr. re-checked her and said she was cleared for PE and then next week would be ok for cheerleading. My question is that the last few days, she s has a lot of nosebleeds....at least one per day, sometimes more than one. She also has asthma and allergies and does periodically get nosebleeds but not this often. I just don t want to miss a connection with her having had a head injury recently. Should I be concerned?
