Thanks for those links, it gave me a name for it rather than 'weird bug crawling sensation'

After reading those pages I spent a couple hours researching 'formication' to see what fixes are out there, but from what I've seen there doesn't seem to be anything if it's due to a psychological cause. It can be a side-effect of certain medications or a withdrawal symptom over certain drugs, but I don't take either. It can also be a hormone-related symptom of menopause, but I'm not old enough for that, and I'd be the wrong gender too.

It may be something that I just have to learn to deal with like I have with the other anxiety symptoms. With any luck it won't be something that remains forever, since it had only begun after that bad week.

Thanks again!
