Bathroom smell seriously affecting my asthma

[lizardlace]

Hey guys, I have had a smell every now and then appearing in my bathroom since I moved in back in May. It has been a lot stronger and more frequent since I had my bathroom replaced last month. The annoying thing is that no one I have asked can smell it, I have super hyper sensitive sinuses when it comes to various things such as chemicals or smoke. I was wondering at first if downstairs is smoking or burning anything, but after flushing my toilet just now the smell completely disappeared. It's been bugging me all evening and it sire as hell will bug me when I wake up in the morning. But the smell diesnt always disappear when I flush the toilet and the smell doesn't come through the kitchen drains (they are connected to the bathroom)


Any ideas? I have no clue what to do and its making me ill
