If your finger is a bit swollen and you can’t get a ring off your finger (and you need to!), this hospital trick might be just the tip you need. If a lubricant like Windex or WD-40 doesn’t work, then just grab an elastic band. Here’s how the method works:
Essentially, you wrap the elastic band tightly around the finger, moving toward the ring as you go. Once you get to the ring, try to feed the band through the ring. Once you do, you should be able to start unwrapping the elastic and it’ll bring the ring with it. Check out the video to see it in action (skip to about 1:35 to get to the demonstration).
