I had my appointment yesterday (was tested for overall allergins and discussed what cause my reaction in April - which is still unknown, BTW and now I need to keep an epipen with me at all times) and it was informative. They did an overall test for me for about ten different allergins (mould, enviromental and animal) to see what would have triggered it. I am still allergic to everything, including the test thats not supposed to give a response! I'm still itching from the dog allergen, despite showering when i got in and this morning and having taken my one a day antihistamine.
I forgot to ask about the probablity of having regular injections, but others (all adults, as we have a seperate childrens hospital in Sheffield) going through similar testing (but not knowing why they had been referred in the first place) were having discussions with the nurses about seasonal injections. So it can happen. One was worried about what would happen on his trip to florida with his family.
I would definately have the discussion with your GP once you have arrived and registered and see if you can get a referal to the Immunology Clinic at your local hospital. Totally get your current doctor write out a note why they decided shots were best for you and why you should still continue with them. At the clinic, they will be able to go over your symptoms and see whats best for you as well.
For me, change of steroids and getting my asthma under control is their main priority. Just adding another inhaler has made me feel 100% better than the day before. Im being referred back for some follow up work and then in 6 months a final follow up.
PS I'm going to still pin my friend Claire down who is the only person I know worse off than myself with allergies and asthma, what her opinion is.. She used to be hospitalised for months as a time when she was a child. I've not seen her much due to holidays and her work, but you are on the back of my mind! I promise!
