4 doctors agreed: See your doctor.: Kidney stones hurt and you should have pain medication to get you through them. Doctors usually get imaging on the stones to find out their size. If they are more than 7mm they're not likely to pass, less than that they likely do in less than 2-3 days.
Re: how long does it take a toenail to grow back? A big toenail can take up to 12-18 months to grow back. Find yourself a good nail tech who specializes in sculptured acrylic nails and have them sculpt a toenail for you. This can be maintained until the natural nail grows back.
As long as there is no permanent damage to the nail matrix or nail bed, the nail ought to entirely regrow and appear completely normal. Fingernails grow at rate of .13 inches per month. Toenails grow more slowly, usually close to half the rate of fingernails. Fingernails can regrow entirely in three to six months.
