If you aren’t able to remove the ring, check with a medical professional.
Don’t try to remove the ring if the injured finger is swollen, painful, turning colors like blue or purple, or if there is no feeling in the finger.
In these cases, the ring may be acting as a tourniquet, stopping the flow of blood. This may cause permanent damage to the finger without immediate medical help.
Summary
To remove a ring that’s stuck, try using ice and raising your hand above your head. You could also use a lubricant to make the ring easier to slip off.
Sliding a string under the ring, wrapping bottom end around your finger, and unraveling it from the top down can also help you slowly pull off the ring.
Seek medical care if your finger is injured or if you can’t get the ring off after multiple tries.
