I don't have MS but do have a problem that is fairly similar in many ways.

I also get phantom smells. I am always convinced that I smell, even when I have just gotten out of the shower. I always ask my mum if I smell and she always say's that I doesn't but that never re-assures me. It's sort of like i've developed OCD or something similar!!

I can also smell gar exhaust fumes a lot. Even if I am just sat in the house, I can smell petrol and fuel sometimes. No-one else can smell it other than me. These symptoms only started when I fell ill ... I NEVER suffered from them beforehand!

I don't tend to hear strange noises a lot but sometimes I get a ringing or buzzing sound in my ears that is very frustrating and is a bit like Tinitus (sp?).

Thank you so much for posting this ... I always thought I was strange but now I know that others get this also! I'm sorry that you all have to deal with this strange symptom as I know how frustrating and annoying it can be!!
