HELP! Who is responsible for moisture problem in new home? It's making me sick!?

I just purchased a first floor condo. There is carpet in the bedrooms. I got sick when I started sleeping in the master bedroom. My eyes swelled up and my throat began swelling shut. We tore up the carpet and there is a definite smell of moisture and mold and it looks like punk wood under the sub floor. There was a sprinkler head right next to the air vent for under the building and this bedroom. I reported it and it's been capped off, but there is obviously problems in more than just that one area. I then started sleeping in the guest room on the other side of the condo (also has carpet). I developed a horrid headache from sleeping in there. I'm running out of places to sleep. Who do I contact? I had it inspected, but the inspector didn't pull up any carpet or check in the kitchen closet, which also appears to have moisture damage, because the previous own left a ton of things stuffed in the closet. The seller's agent never left me alone in the space so I never felt comfortable doing any serious poking around. I'm really sick and don't know who to contact or what to do. I'm no longer speaking to my Realtor. What can I do? I contacted the property management company and they're having an inspector come in, but I'm afraid I'll get taken advantage of again. HELP!
