My 5 yr old son we discovered is allergic to dust mites. Mostly with a sinus reaction and eczema. Once we cleaned up his room it all went away. But if he plays in a pile of stuffed toys/material he will get a runny nose and watery eyes but they clear up as soon as he gets out of the stuffed toys for a bit. Well yesterday he spent 4 hours on our bed watching tv. (we have to get our house done in time for the mortgage and are on a big deadline) When he got up I noticed he was itching all over. He was red all over and puffy around his face/eyes. No sneezing and no watery eyes. The rash was interesting because wherever on his front he had only 1 layer of clothes he was red and itchy but normal where he had two layers (underwear area or where the pockets are on the front of his pants). He was also not as bad on his back, but still red in places. He was laying on his stomach. Our bed has a foam type 2 inch pad on it and there was no sheet over it yesterday. I put him in the tub and washed everywhere but his hair/face. By this morning his body is almost totally better but his face is puffy and red. Our first thought was dust mites but it is not acting like his dust mite allergy. Plus the bed pad is not more then a month old. Latex is our next thought. I read up on it last night and it was talking about people with latex allergies having certain food allergies. Potatoes was one. I suddenly was able to put a connection together. My son always gets red itchy hands when he eats chicken & mashed potatoes. We had ruled out the potatoes thinking - who is allergic to potatoes. But we were never able to pinpoint what caused it. Now we believe it is the potatoes. Anyway back to the bed. The only other possibility is the spot my son was in is the cats spot. The cat lives there 20 hours of the day. So cat is also a possibility. But we have 2 cats, 2 dogs and a bunch of horses and he has never shown any type of possible allergy to any animal. By some miracle we have a doctors appointment tomorrow for DS. Talk about timing. But I wanted to know if anyone had any thoughts about this. Thank you!
