lots of people have problems with ezcema treatments, for instance diprobase causes instant hives and redness in my teen daughter.
that is a huge list. a lot of protein foods not on that list.
fur and feathers do count. its part of the package really.
however, dont give up hope for outgrowing in the years to come. it may take some time, our son is now 16 and we have only just been given a chance to reduce his list by a substantial amount. He will always be an allergic person, carrying epi pens etc, but his future adult life looks easier than his childhood one allergy wise.
the skin rashes seem to be a permanant part of being a multiple allergic person, my son for the first five years used to hive up and get a rash almost weekly. This was due to accidental ingestion as part of a food reaction to a new food. Or from environmental allergies, such as running under trees during tree pollen season. jumping on a bed (dustmites) etc. He also had an airbourne response at 2yrs if he stood next to me in the kitchen when i fried an egg.
He also had at one point a severe dog allergy. and would have throat closing and asthma symptoms if in prolonged contact with a dog/ or in a room/house with a dog. Both these airbourne reactions are now outgrown.
i learned to simply wash the skin to remove irritants, and apply ezcema cream to the flare up area. ( hives, then when they died down = ezcema.)
Often he would continue to play and be happy even when this sort of thing happen, so I took that as a sign that little was wrong.
I focused on making his bedroom and home low in his environmental allergies, and of course, his many food allergies.
what medical help are you getting? if severe rashes, note date down and mention to your medical support. which is , hopefully a pead immunologist at a kids allergy clinic.
hope this is helpful.
