Yes, Vicks Works very well. You don't have to be "slipping & sliding" for it to work on the feet, just massage a little on the soles. Who cares how it works, only that it does, although if you look at foot massage charts, it may have something to do with the centers of your body that receive energy from your feet.(?)
Also, if you use a nasal spray-rinse, it will help clean out the nasal passages & all of the sinus congestion.
And, it may be to late for it in your case, but I have used "Zicam" or zinc based cold meds to help shorten the length of a cold. Just DO NOT take this on an empty stomach. You will be barfing it up, and causing a whole other issue. (Yes it happened to me.)
Good Luck & happy quilting,
Susan
