I'm glad its sorted. Mind you, irritations can be a nuisance. I have to be careful and only use deodorant that is aluminium free, otherwise I itch all over. I can't walk through my local Boots perfume depart, the scents make me feel as if I'm going to have difficulties breathing. I now hold my breath and walk through as quickly as I can. The only chemical that really affects me badly is sugar soap. I once touched some with my hand and my skin felt like it was in tensly burning! Luckily, I've never come in contact with the stuff since.
One of my drinking mates from our University, its his specialised field, has always said the ordinary household chemicals and stuff we put on our skins are always the great unknowns in our lives. Some have been researched properly but most haven't according to him.
