desperate for answers

My son has been suffering from severe asthma for 11 years. He has had asthma since about 2 years old, but at the end of his second grade year he got pneumonia, and that has left him with the more severe issues. For 11 years now he has been in and out of hospitals in 3 states, on multiple medicines and controllers, but never gets better. No answers given, no further help given: just a constant go around of "Here, try this!" He can't hold down a job because he is constantly having to take time off due to bad attacks. I don't know what more to do to help him! Nothing helps! Now we have just moved to a new state, have no insurance, and he has already been to the local ER with nothing lasting to help.
