Anything can trigger eczema.....
For me, it's that stupid tick....
Unfortunately for eczema/dermatitis, once it started, you will
just have to deal with it.
I recovered from my bad rash when I was in Sec school
Took me a year and 5 yrs to fully recover
I had to go to my doc for monthly shots followed by quarterly
than yearly shots
And after that I just recovered :x
I think that shot was like 100 plus per shot leh. Dunno what it
is also.
