White misty patches on old blocked chimney breast walls?

I'm really hoping someone can help me! I live in a 100 year old house, and in my bedroom I have an old chimney breast, which just looks like normal walls now. I've only lived here for 2.5 years, but since I've been here a large, white misty patch has appeared at the top of the walls. I wiped it over with some tissue around a year ago to see what it was, and the tissue was wet, so it seems to be tiny water droplets. It's since come back again, worse than before. I'm concerned because I'm having a sore throat and bad chest when I'm in my room at night, and I'm wandering if this could be the cause? Could anyone tell me what these white patches could be? I can supply photos by email if needed. :o) ************************** Reply to mdp gas services.......... Thanks for your answer! Yes, it is fully bricked up and plastered over. It goes down into my living room too, and it's bricked up in there as well. I live in a rented property, it's Bournville village trust in Birmingham, so they have to fix it don't they? What sort of work will need to be done? I don't want to contact them until I'm armed with all the info I need, as i think they'll try to fob me off with just painting something on the wall. We have patches of damp on joining walls of 2 rooms upstairs by the ceiling, and rather than go in the loft to see if there's a problem, they just painted stuff over it. I'm sure this house is full of some sort of damp or mould!!!
