I've had hand sores for last 2years, came on sudden. I tried umpteen creams. It's bad but scalding hot water relieves the itch but obviously causes more problems, but ohhhhh the relief for those few seconds.
Dermatology prescribed dermol for washing with which I use for waahing hands and I use aveeno in shower and to soothe.
Also prescribed enstilar foam and elocon cream. They both work but the elocon clears as it's on skin, get a few days reprieve and returns but it's made a difference. Only thing is I put on and sit for an hour and can't do much as hands all cream.
I got patch test and as pp said about methyl, I found I was allergic, as well as nickel, cobalt another can't recall.
I use latex free disposable gloves, marigolds and switched to ecover products which I've found are actually better than big brands like fairy, however not all ecover is free of the methyl but the washing up liquid, anti back and bathroom cleaner fab and last a while.
Lots of products contain this chemical but the website SKINSAFE is good for highlighting which products are free, though some people have allergies to these too but they're obviously allergic to another ingredient also. I use E45 to moisturise as have dry skin on eyebrows too. Estee lauder products. Boots brands such as Natural Collection, No 7 and 17 and maybelline are all free of methyl.
Lorreal shampoos are free too, luckily most of the products I already used were free, it was the cleaning products that I used which contained it.
Child's farm and hemp cream from body shop didn't work for me, but the aveeno and elocon are good. I just don't like potent creams on my hands as I'm afraid to prepare food afterwards and of course you spend a long time washing afterwards which then irritates the skin. Just can't win.
The itch is indescribable and the fact it's on your hands which we use for everything is so annoying.
It's so good to find others who have the same issues as you can feel so isolated when nobody understands the sheer torture you go through daily.
Dermatology not yet sure if I have psoriasis, eczema or something else but I do have auto immune conditions and these can trigger skin problems. Psoriasis runs in my family and I recall seeing relatives and felt so sorry for them but relieved it wasn't me. Now it is.
The only thing I can recommend is try anything and everything as what works for one person doesn't for others.
