Smelling burnt plastic?

Just a short update on something weird.

Since Monday, 4 Jan, my sense of smell seemed to have gone haywire. I kept smelling burnt plastic or wax, or what?. I couldn't seem to put a finger to it, and when I asked my kids, their responses were, like my youngest put it - 'Mummy, it's only you. We don't smell anything like that.'

I have noticed that after being on oxygen or chemo or a combination of both, my sense of smell was not so acute anymore.

I noticed that even when I am outside the house, I am still getting that smell.

It has already been 3 days now and the smell is still there. So, I don't know what is happening.
