One of the first things I do when I see someone with an injured hand or finger is remove any rings. You’d think the person would have already done this, but sometimes it’s hard to think straight when you have an injury. Also, many are afraid it’s going to hurt (it can), and some think the finger has already swollen too much (sometimes it has).
But the thing is, with a badly swollen finger, the ring acts like a tourniquet, cutting off the blood supply, and you could end up losing your digit. What to do?
If you’re in a situation where you can’t get to a doctor, you probably won’t have a ring cutter, but you might have an oily substance or some strong string or tape. So, here is one nifty trick on how to remove a ring from a swollen finger
The method calls for wrapping the affected finger tightly with the elastic strap, then threading it underneath the stuck ring and being able to remove the ring that way.
Neither of these methods should be attempted if there is an injury on the finger, or if the patient cannot handle the pressure of the wrapping up of the finger.
