Hit my head on the ground front on on Sunday, since then have been experiencing vertigo like symptoms - disoriented, dizziness, headaches, nausea, unsteadiness, tiredness. I cannot move my head in any direction quickly without nearly falling over. Feels as though someone is5 moving the ground from under my feet, room feels as if it is spinning when my eyes are closed. Get hypertension each time i stand up, sometimes resulting in falling over or body starts convulsing on the odd occassion
