Um, hon, if your ring is cutting off circulation then it is probably too small for that appendage. *blinkblink* That said, I wear rings on both of my thumbs. It took a while for me to get used to them (I still haven't realized that I will scratch myself with the rings if I drag my hand across my face *headdesk*), but now that I am, I can't not wear them. It's a thing. *shrug*
