G'day Tootsie,
good to meet you.
I have Restless Leg Syndrome which does affect my feet as well. There are some medications which can actually make it worse. If this is something new, it might be worth speaking with your doctor in case it's a side-effect of a medication you may be taking for something else.

It's an awful (dreadful actually!) feeling to have, esp. when trying to go to sleep. There are a few things to try that might assist if it is indeed related to RLS. I find if my feet or legs are too hot then it's a big trigger and also if I eat too much salt (even hidden salt in foods). Caffeine also. I'll post the link to the RLS Foundation website. It might give you some ideas.
