I posted about my ring callous earlier and found a solution.
If anyone else is having their ring (particularly if it's too big) rub against their finger and cause this uncomfortable rought patch, try the Nivea Soft "refreshingly soft moisturizing creme" in CVS/ Walgreens. It's 99 cents and comes in this lil container you can fit in your purse. I started using it last night and have noticed an instant change! Not trying to advertise or anything, but it's worth a try.
