Ouch! That totally sucks. Sorry to hear.
That's just one of the reasons I don't wear my ring.
Another reason is, one time I got a nasty bug bite on my ring finger and it began swelling up...it might of been a mosquito, spider, hell I don't know, but it was itching and swelling. Anyway, a short while later, there was no circulation and it was turning blue. A lot of ice and soap later, it finally came off, but I thought I was going to have to cut one of them off...the ring or my finger.
Then again, I just don't like rings. I'm not good with hand jewelry, I do too many things around the house, boat or truck without even thinking and I end up trashing them and scratching them all to hell.
