Hi Lotte, its heartbreaking when our children are ill and we feel so helpless when nothing will help or makes them feel worse. I get the same reaction as your son when using creams (burning skin and red colour to the skin). Mine also feels tight immediately after putting any kind of moisturiser or skin cream on my skin and i have a massive flare up anywhere that the cream or lotion touches. I have tried everything, any aqueus cream, sudacrem, e45, they all did the same thing, even though they are supposed to help. It took me a while, but i have found something that helps a little and you will laugh when you hear it and think "why didnt i think of that". Try Aloe vera after sun gel (must be water based gel, not cream) this helps my skin to feel cooler, it doesnt stop all the itching, but it does soothe enough that i dont get as stressed.
This could help your son calm enough so that being upset isnt aggravating things and making it worse. I know when i am stressed or upset i get more breakouts.
I have suffered since i was 9 years old, my first breakout was caused by a simple horse ride. That lasted a few days and because the horse ride was a one off treat for me, i didnt get my next breakout until i was 14. That one was worse, it lasted on and off for 3 years and was triggered by getting a dog, i would get a breakout every month or so. Back then there wasnt much they could do, told me it was hives and that i just had to put up with it.
Over the years i have had more breakouts, but was lucky. By age 26 i was free and clear, and that lasted until july 2012 (about13 years) when a minor surgical procedure triggered this last episode. Im coming up on 3 years with this episode and its been the worst i have had so far. I Suffer multiple breakouts every day, usually between 20 and 30 a day. I have been on multiple therapies, but none have cleared it completely, they do reduce the severity, they just dont clear it completely, which is why I have been classified as treatment unresponsive by my Immunologist.
I think it would be helpful to you and your son to discuss seeing an immunologist with your doctor. Your Son is young, so they should be able to help him so that he can enjoy his childhood. Urticaria has many causes, and the fact that he has excema already shows that he has issues with his skin. The steroid treatment for excema might help the urticaria in the area that the cream is used.
An immunologist can identify his triggers (causes of urticaria breakouts) by doing a full allergy screening. This will then help you to remove triggers from his environment. Foods can trigger Urticaria, and i empathise with your dilemma about removing things he likes. My son is autistic (adult now) but when he was a child he was very picky about what he would eat, to the point that his diet was very restricted. I had to try everything i could to get him to eat healthily. There is a fruit based product on the market that might be worth you trying. You might have seen the adverts lately for fruit bowl?? this has been out a long time and my son loved their fruit bars, its pure compressed fruit. I used these as a treat instead of sweets and chocolate with high levels of e numbers and artificial flavours or preservatives. They might be worth you trying.
I hope that you can find a way to help your son to be able to enjoy his life and get treatment that means he will be happier in himself. Good luck lottie
