Wat's wrong with my ear?

Feeling a bit xian recently..think it might be due to my ear problems again..

This is like the 7th or 8th time(minus the many times within 1 incident) that i had to seek medical help for my ear..i seriously dunno wat's the cause or the prevention..

My local doc says it's 'nothing to worry about' and the ear is generally 'self-cleaning' and doesn't need external help(like ear candling - something i've always been tempted to try..but resisted for fear of my ultra-sensitive ears. The few doctors i saw in UK says ear problems are more common among swimmers(i'm not!) and people who use cotton buds - this i''ve cut down drastically ever since i started having ear problems a couple of years ago..so i'm really quite helpless everytime it occurs..

Granted, it's not life-threatening(though hearing might be affected in serious cases)..but it's bloody uncomfortable..besides muffled hearing..i tend to speak softer than usual..cos the sounds will be louder than normal in my head..as most people know, i already have the on-off habit of mumbling..imagine i mumble softly..people are just gonna hear 'shhh..ttbbb...cchh..'

For now, i can only try out the prescribed ear drops and hope for the best..
