No advice for the rash and puffy eyes, and this may not be the case for you, but worth mentioning. We had been treating my son's allergies for years, and things seemed to get mildly better with meds, but nothing gave him true relief. He sounded stuffy all the time. It was like he constantly had a cold. Everyone chalked it up to Texas allergies. He was also a snorer, which the doctor said was related to his allergies. His last check up (my son is now 9), I pressed a little harder and the doc referred us to an ENT. Come to find out my son had HUGE adnoids and enlarged tonsils. And his slight allergies seemed like horrible allergies because he already couldn't breathe. When seeing the ENT, he said he was surprised my child did not suffer from ear and throat problems or didn't get sick often...he said there was a correlation. After getting his tonsils and adnoids removed, the snoring is gone and he is more rested. We haven't had to do ANY allergy meds A. all. So this may not be your child's case, but might be worth looking into.
