I have mold exposure symptoms after spending a significant amount of time in a mold room... Lawsuit?

Hello. I work in an office and about a yes ago, following a storm, one room sustained considerable water damage. Since then, mold has been growing all over the walls and floors and ceilings. I spend about half my day alone in this room and I have been experiencing fatigue, nausea, head aches, hair loss and pain. I am considering these are related since I have been researching it. I have tried to tell my employers to do something about the mold but they won't. I complain almost every day. Meanwhile, I have to take sick days due to my symptoms. Do I have a case against them when it comes to my pain and suffering from mold exposure?
