I just made a long post of my own under Social Chat.
I wish I knew how to get others to understand your sick and there are things that are going to make you sicker.
I finally found something on MCS yesterday that some what got thru to DH. It said that these chemicals/fragrances that most others came be around and don't bother than that a person with MCS is 1000 times more sensitive to those chemicals/fragrances. I told him that was why I could even smell them when he couldn't.
I don't know if there is anyway to get thru some people but I'm always looking up stuff on it hoping I can find something.
