4 yrs ago I suffered a hit to my forehead where I blacked out for a few seconds, slumped over, muffled hearing, & spots before my eyes. Since then I have had dizzy spells & headaches regularly, short term memory loss, sharp pains in my head. I have been seeing a neurologist and so far she doesn t know what is wrong with me. I have had almost every type of blood work done, 3 CT scans with and without contrast, & a EEG which are all normal! I don t know what to do! I even started keeping a journal recently as symptoms happen and it is way more then I thought! What should I do or get tested for?
