Just wondered if anyone else has experienced this my son has just been in hospital with pneumonia, has been on iv antibiotics drip, has not eaten for a week and has been really poorly.
The good news is he is bouncing back now and getting better, the bad news is that his allergies seem to be really bad. Today his face and hands have had bright red patches on them with small hives. He has not eaten anything different than before he was ill, in fact nothing has changed. Also during his illness his eczema disappeared and now its back badly. 
He had confirmed allergies to egg and milk and we are discussing coeliac testing with his doctor and he is not eating wheat at this time due to how ill it makes him.
I am obviously so glad that he is getting better but he has only very small amounts of food and it scares me as I have not got a clue to what he is reacting to. Just wondered if anyone had experienced this sensitivity after illness too. Thank you.
