The symtpoms only come after being in one room at work. I get a heavy chest that lasts all night even hours after being in the room. I sometimes loose my voice, but am in no real pain. In the mornings (only after being in the room the day before) I have a stream of blood in my nose that I spit out. My boss has promised to test the air (new ventilation system put in recently - I had no problems before!), but they don`t know what to look for. What can be the cause?
