Hi manna,
My ds is 2.3yrs has a severe egg allergy & dairy allergy too. Very similar symptoms, as soon as he ate scrambled egg, he had blotches (big red blotches) which started from the mouth then spread all over his body, after a while he went green & was violently sick/projectile vomiting.
This was the first time I had ever tried him with egg & he had already had an allergy with milk - I BF him myself for the first four months and then during the transition to SMA I found similar problems although the blotches were like hives so he had SMA Soya milk until he was 2yo.
If he has part of a cake or a biscuit with egg in he his mouth becomes blotchy straight away (not v severe but enough for a mum to take notice IYKWIM)& I saw my local doctor, he referred us to the doctor at the hospital who advised me to keep him off of any dairy products or products containing egg until he was 3yo.
Apparantly by carrying on feeding your child what they are allergic too, even in small quantities & if there is no obvious sign of a reaction (like he never had a reaction to yoghurts although he has soya yoghurts now) it keeps the allergy alive within them. They are hoping he will grow out of it as his body matures.
Also, when he was a baby he had quite bad eczema and seemed always ill, the runny nose and eyes that you mentioned before which is all part of the allergy. And he never slept well of a night time.
I saw this doctor at the hospital when DS was 14 months old who advised me to change his diet, his diet takes a little getting used to soya margarine, certain meats and crisps, soya ice cream etc but I can honestly say I am very pleasantly suprised with the results, he has gone from not sleeping well to having 12 hours, if not more a night - his eczema has gone - and he is generally well and doesnt have any of the above symptoms any more. Its amazing.
They tried to take blood from him when he was about 15 months old to test for allergies and what he was allergic too - unfortunatley it was very traumatic as he was(and still is) a chubby little boy and they could not find any veins so they tried taking blood from three different areas, then moved on to his ankles and were still unsuccessful - so this was something we may be able to complete when he is a little older, although its very obvious from the reaction. Interestingly enough hes at that age where birthday parties and Christmas seemed unfair and he pinched a choc something or other from the table, not my party (as I try to do food he can eat too) but a friends - and he had runny eyes and nose still so in a way at least I know its still present in his system.
Also, regarding the MMR which was mentioned before, for different reasons I did not want DS to have the triple (which I wont go in to here) although I felt it important to vaccinate him - part of the reason was the triple vaccine is bound together with chick egg - and some single vaccines. My mum and I travelled to London from Ramsgate to get the single vaccines, the doctor administering the vaccine was fantastic and it was a vaccine that was 'egg free' not bound together with chick egg all of which we have documented from them. Although expensive, it was complete peace of mind.
He doesnt seem to have a problem around pets or dust mites etc. The doctors surgery provided me with piriton syrup in case of an allergic reaction to anything else, stings even prickly heat especially useful in the summer.
I dont log on here as regularly as I used to (due to not having a computer! but as I am particularly interested I will try to look out for any replies. I hope what we have been through with the allergies will help anyone else looking for a little advice..
If you would like my email address to chat further then let me know, hopefully I can be of some help.
