NeuroTalk Support Groups - strange symptom

This is really strange and I can't understand what's going on. Lately, I have been smelling a really strange smell. I thought it was something I was using, like my shampoo or conditioner or something. I seemed to be noticing it all the time. It will come and go. I noticed I would wake up in the night smelling it . I smell it at work or when I'm out from home anywhere. I started to believe maybe it was my wash detergent or softener. But I don't smell it on my clothes and I used everything completely different when I did my hair last time. I still smell it. No one else smells it on me . It's driving me nuts. I've googled and I have seen simular symptoms but no one actually says what the cause is. I'm thinking that it must be coming from inside me and that scares me. Has anyone heard of anything like this or had these symptoms? I haven't asked many people about it because the ones that I have mentioned look at me like I'm nuts. It's a really sweet smell and it's really strong at times and sometimes It's mild. Any thoughts would be so helpful.:confused
