I cannot comment on the likely response from the CAA as I do not have the necessary knowledge. It seems to me however that what you need to do is provide the proof, or lack of it, as to whether or not you actually have asthma so here is what I suggest. Go to see your GP and ask him to do several things:. .1 Provide you with a Peak Flow Meter. You will need to do readings at least 4 times a day and for several months, particularly through the "Hayfever Season".. .2 Ask him/her to do your IgE levels. This is a blood test which will reveal the presence or absence of an allergy. Raised levels indicate the probability that you have one. Your Dr should ask if you have any ideas about what the allergen may be eg you may find that your hay fever is worse when you walk through, or near a field of grass or cereal crops.. .3 If anything proves positive ask about the possibility of desensitisation.. .4 You mention that your shortness of breath occurs at night so it might be a good idea to check the possibility of Housedust mite allergy.. .Hope you find this of some help. Good luck with the CAA. <img src="smile.gif" border="0"> . .PS Let me know how you get on.
