I was not trying to offend you and i doubt the other poster was that said the same thing was either.
I was simply saying if a medical condition is so severe that it requires out of state travel every year to control it maybe you should be looking for more medical support (maybe you need to spend the "travel" time visiting national specialists). I am sorry to hear that the best doctors in the area can not help you - how sad your son has to feel like this. No child deserves to feel so horrible.
My statement simply stated - what is going to happen if a vacation is not possible - what if when he gets older his employeers does not understand and does ont allow the time off work? Maybe the PP is on the right track - maybe a permanent move is medically necessary for your son.
When it comes to severe allergies, there really is NO treatment except to hope that over time and with exposure the allergies will get better.
I have a severe allergy that they cannot treat. I did allergy shots only to have them make me even sicker because he natural amount of my allergy in the environment was already more then my body could handle. My allergy shots were at 1:1 millionth concentration and I STILL reacted after each shot (head to toe hives, sleeping 18+ hours a day, it was fun). My allergy is present year round, except in the very very dead of winter (as long as its stayed below freezing for several days).
Today (almost 14 years after my allergy was first dx) exposure has lessened my reactions. I still react, just not as bad and I can handle more exposure now then I could back then.
The only advice anyone has been able to give me beyond medication (which traditional allergy meds do not control my symptoms at all, singular does a decent job at it and controlling the asthma symptoms) is to move to a different location (southwest, Colorado etc) and OUT of the midwest river valleys. it's not always possible to just pick up and move far away. FURTHER, for people with really severe allergies, there is a very high likelyhood that you will just become allergic to something your exposed to in the new location (this is what happened to me, when I lived at home with my parents my mold allergy wasn't very bad at all and rarely bothered me - hives when mowing the lawn, and my biggest problem was corn pollen, I went to college and the mold allergy just went bonkers due to the change in location)
