I recently had a bit of an unpleasant experience. A wasp had stung me just by the ring on my left hand, and, as one does, I just ignored the fact. Wasp stings aren't nice, but they're no big deal.
Two nights later I woke to find my finger actively throbbing. The whole thing had swelled and my ring was cutting off the blood supply. I went downstairs and tried to remove it.
The bloody thing wouldn't budge, and all my efforts had made it worse; my finger was now purple and painful. I didn't want to cut the ring off, as it was a prized gift from Lady M.
I then spent the rest of the night with my arm in the air, hoping that this might drain some of the blood back down into my arm,and reduce the swelling.
The following day I tried again to remove the wretched thing, and after squeezing it with some pliers to make it rounder, it eventually came off; it was a very painful experience.
THEN, a couple of hours after I'd removed it, I was stung by a bee; luckily nowhere that caused any similar problems. The swelling on my finger subsided after about three more days.
C'est la vie!
