Warts on your hands
Warts on your hands are caused by one of the many different wart viruses. They start by being little fleshy lumps anywhere on your hands, which gradually grow larger. If you bite your nails they particularly occur around the bottom of your nails. Most them will go away if you do nothing - in about three months - or you can 'paint' them with special wart paint that you can get over the counter at the chemists. If they still don't go away - getting them frozen with liquid nitrogen at the doctor's surgery can help get rid of them.
