I need help!

wrap an thickish elasticish string around your finger, slide it under it, then spiral pull the string until it comes off

Bolt cutters just below the ring

Fairy liquid, put your hand in oil, some people used elastic bands under the ring and twist it off. Some people use string. The best thing is to hold your hand up to allow the blood to drain away from the area whilst you are doing this too.

First let the swelling go away by putting some ice. Second apply oil or soap or butter. Third tie a dental floss or thread above the ring area so the ring can be pulled out.

Dishwashing liquid.

Go to a fire station and ask there, honestly most have a tool to do as do a lot of jewelers.

Soap and water ... worst comes to worse file it down

Try a antihistamine/hayfever pill to bring the swelling down.

Butter or soap

Are you okay now?

Or a moisturizer

Oil helps.

Soak the hand the ring is on in cold water.

Try soap or go to casualty
