Hi ! I have gone through your questions and I understand your concern . I would say that these are normal symptoms of a minor head injury with no brain damage that will resolve in few days . But I suggest that if you have any of these symptoms or if you will have in further days , you should go to the hospital : - loss of consciousness. -Vomiting -Worsening headache -Dizziness with most of balance . -general weakness -sleepless or convulsion -problem reading or talking -irritability -visual problem like:blurred vision or double vision -loose of .use of any part of the body:weakness in arm or legs , numbnes, tingling. -any sign of bleeding from nose or ear. In this case they will do a CT of your head to see any brain damage . Hope these help! Thank you for using HCM
