I have eczema. I get it from stress and also certain soaps (dish and laundry to be more specific) I also have had a problem with severe dry skin on my index finger. I have narrowed it down to laundry soap, dish soap and latex gloves. But it will get so dried out it will crack and bleed. It does not itch. It is different from eczema I have learned.
The exact cause of eczema is unknown, but it's thought to be linked to an overactive response by the body's immune system to an irritant. It is this response that causes the symptoms of eczema. There is a higher instance of it in people with allergies, but that can be because the immune system is already stressed.
It's a skin condition, but outside influences can make it worse. I'm not sure allergies would make it worse, but anything that dries your skin like harsh soaps will. Winter air is drier, and that will cause it to be worse as well.
Kinda for both on some people had it just put plenty of special lotion on it every day and it will slowly but surely clear up, and i had it and was allergic to cats at the time it got a little bumpy but i was fine, its a SKIN CONDITION/ ALLERGY - Hope I helped!!
My faence has it and we just recently went to the doctors for it... They say It is a skin condition caused by stress and many other aspects. It can go away by itself but will come back at times of stress. They can give you an ointment to make the rash go away or to calm it down. Hope that helps : )
