Your symptomatology suggest that you might have suffered or suffering from TIA involving right MCA
. You have done CT scan already, which is reported normal. I feel if your symptoms are suggestive, if there is positive clinical examination and there high suspicion of TIA by your PCP, then I think you should be started on Aspirin. CT scan always does not detect a bleed or clot. Investigations like CBC, PT/PTT needs to be done to evaluate the etiology of TIA.
