I've seen about every doctor possible and finally got a diagnosis of Mast Cell Activation Syndrome (MCAS). The doctor said many of his patients suffer from mold. He recommended a whole home mold inspection.

The inspector only discovered mold in the air handler itself, which isn't too uncommon. We could have just cleaned the handler coils but decided to pull the entire thing just to be sure. Only after it was pulled did we see about a 15 foot long stretch of mold going directly into our ductwork.

In the bedroom we were replacing our carpet with hardwood floors and discovered a 10 foot mold stretch behind the baseboards.
