Hello, I am 34 years old and have been having dizziness/vertigo since a week. My head aches at the lower back sometimes and I suddenly feel vertigo for sometime, unable to look at the screen or sunlight for a few seconds or the room looks spinning for sometime. I have got my blood reports and all are normal, I got it checked with ENT, they don't find anything abnormal, they have referred me to neurologist, I have to get it checked by him. Could you please tell me the possible causes? Treatment? Is there any major concerns? My BP and Sugar both are at normal levels and no history of hospitalisation. Please advise.
