Q. Can mold exposure cause an ear infection?

Hello doctor,

Last year, I noticed that my 3 year old's tonsils were very large. I contacted his doctor. But, he could not find anything wrong. I later noticed him yelling or talking loudly and asking me to repeat a lot. So, I had a hearing test done and he failed. They explained that he had a fluid buildup behind both the ear drums and that his ears needed a cleaning. So, I scheduled that. Early this year, his right ear drum burst and he had a yellowish-green discharge. A month before that, we had hired a mold inspector because I was falling sick more often than usual. I found the mold and had it tested and it was a Chaetomium mold. It was growing right above the intake vent for my heat and air. Now, he is scheduled for surgery. Could the mold have caused this? And who do I contact to have a testing done?
