Left eye swelling in infant

[Mommy22QTs]

My 14 month old daughter was perfectly fine on Saturday, no illness. She is taking Amoxicillan for kidney reflux after being allergic to beoth sulfa and nitrofurantin. She has been taking Amoxicillan for 3 weeks with no problems. Saturday night had not given her meds yet she walked up to me with her eyes closed, I picked her up and she acted as if she were going to sneeze. She did not sneeze but went limp in my arms and her eyes were fluttering a little - she never went unconscious but was VERY lethargic we called 911 but before they arrived she had come out of whatever had happened but her left eye was almost swollen shut. Within minutes the eye was almost back to normal but still swollen a bit. She had another episode at the ER and again the eye thing happened. The next 8 hours in ER no more of the lethergy but repeated eye swelling - transient - coming going - severe at times. They did a CAT, a chest x ray and blood work, they found nothing, we came home next morning and she was 100% fine for a while then the swelling again but not the episode. Now Monday nothing today at all. I don't know if this is even an eye question but can you help. My doctoe has no idea, the ER doc no idea, a pediatric allergist the same?? Thanks
