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.
Healing Ingrown Toenail. I know that an injury towards the cuticle of the nail area takes about 9 months to grow all the way out on your big toe. As far as an ingrown nail, it has to be treated or partially removed before the healing starts. You will feel much better within a day or two, but still takes longer to heal correctly. Warm soaks in saltwater will help ease the pain and heal it faster. Tea Tree Oil is helpful too. It will act as a soothing antiseptic and keeps fungus under control.
