Hi, I am 30 Years old. From last 3-4 months I am feeling light headed and stomach pain. I have a sinus problem also, 2 months back, I had a CT Scan and MRI , Report said number of polyps in a nose are more but ENT specialist said this is OK. But some time in a day, I feel like I will get faint, ear pain, stomach pain. Consulted 2 doctors, they said it is just because of Acidity and they are giving me the acidity medicine but nothing worked. Kindly suggest what can be the reason for this?
