My son has always had major allergies, but we have never had issues with the food allergies, other than a couple of minor allergies to raw egg and tomatoes, diagnosed at age 3. My son took allergy shots twice a week for 9 years and really didn't see any relief from his allergy. From age 12 until 16 he did not receive the allergy shots. This year he began allergy shots again, at the advice of the new allergist we began seeing in May. He received about 4 rounds of the allergy shots between June and July 2011. Around the 1st week of July we had a first episode with lips swelling, tingling, persistant itching and redness throughout his body. We assumed it was something he had .eaten, but had never been bothered by this before. After the 2nd occurrence about 1.5 wk later, we decided not to get another allergy shot until after another visit with the allergist. Mid August 2011 we visited the allergist, by then there were about 4 occurrences of the swelling lips, itching, tingling and redness. Our allergist advised to continue the allergy shots, with 2 10mg Zyrtec at bedtime everynight. Since then we have had 3 additional episodes with what was diagnosed as angioedema. Seems to be getting more frequent, lasting longer, and more severe symptoms, swelling in other areas(noticed in hands and arms now). Should I hesitate to continue the allergy shots against what the allergist advised, as it seems with more allergens we could expect more episodes? I would love to have some other options if there are any? Specialists, etc.....We began keeping a diary, hoping to identify possible food/environmental triggers. We are now carrying an epipen just in case this becomes more severe.Thanks for any input/advise/suggestions.
