I heard or read somewhere that BFS can be caused by pesticides or organophosphates. Does anyone know anything about this?My first severe bout of BFS occurred while I was working at a large metropolitan botanical garden (in the office, not directly with the plants). I was in my early 20s and eventually went to a neuro who gave me a few quick tests in her office and pronounced it benign.For the past 6 years I have lived on a golf course. I wonder if there is a connection.
