I have had a very limited sense of smell for a long time - at least ten years.
However, recently, I have noticed that some smells, once they get through, won't go away. For example, at work the other day kids had been cooking fish pie. It was really strong but I could still smell it (or thought I could) when I got home.
Today I had to put bedding in the wash - cat had been sick on it, DH had cleaned all of the sick off but I still caught a whiff of it and now, six hours later, it is still lingering. I literally had hold of it for a minute, if that, and the washing machine is out in the shed, so no way could it get through to living room.
Have I just got an overactive olfactory imagination? Or is it something more serious?
