You aren't alone Kitty. I do the same. Especially around the electrical outlets.

Doesn't help that my father and his mother both have anxiety related to an irrational fear of fire - and guess what? I inherited this! So for years I'd smell this burning (long, long before the MS was in the picture) and freak the heck out!

Now I know it's likely the MS, but depending on how bad it is, I may still do checking just to be sure.
