I have problems right from the start.I go down about 5' and my ears pop,I head back up and I hear a zipping sound and when I reach the surface air exits my ears .I have pain but it goes away shortly.I also have seriuos pain when I travel by plane(ears feel like they are going to explode)Went to a ENT every thing O.K. Is this an equalization problem or something more serious.He told me to take sudafed and nasal spray before I fly,should I try the same when I go Diving.
