Hi Doctor, I have been suffering from chronic lightheadedness on mainly left side of head and forehead for over 15 days now. Went to a GP, and all reports came back normal, such as brain ct scan, cervical spine xray, blood test, vitamin b12 and d etc. Doctor prescribed Neurobion forte tablets for 5 days, which have ended but to no relief. I am not feeling any pain or headache. I also feel I have somewhat blocked sinus, and my ears are clogged with earwax. Could the lightheadedness be due to the clogged ears? Kindly let me know as I am very worried as there is no proper diagnosis till now.
