Can too much excercise cause chronic laryngitis?

Wow... That's along time to be ill hun, i think your doc should have already recommended you to see a specialist, at least blood tests, swabs... Are you feeling alright every where else but your throat? Just for example, i was suffering with depression and suffered with cold and flu for a whole year and a half! Your current condition sounds like laryngitis. But i would take a trip to the doc and explain you worries... Ask for a Specialist. Good Luck x
