My daughter's MRI came back normal. The doctor says that she must not have had much of a concussion based upon the MRI, if at all. It does seem like that could be the case, because she did not have alot of secondary symptoms. However, she has had a headache every since that day and never had a headache before. She is also tired all the time, spacy, and "slow" in her schoolwork. Perhaps hitting her head has given her a migraine? And the other symptoms are related to the headache? Perhaps the symptoms are related to the pain medication. So now should we treat it as a migraine? Anyone else have thoughts about this, when the MRI is normal?
