Treating Warts

If you have developed a wart or warts at the injury site of a hangnail, treatment may not be necessary, although it's a good idea in order to prevent spreading the warts. Over-the-counter treatments or salicylic acid can be effective at resolving the problem. If the warts prove to be stubborn, consult your doctor, who may need to remove the warts using a liquid nitrogen freezing process, cantharidin treatment (which causes a blister to form over the wart) or surgery [source: Mayo Clinic].

Treating Hangnails

If preventative measures are too late in coming and you already have a hangnail brewing, there are some things you can do to treat a hangnail -- and none of them involve ripping, tearing or biting.

If you have a hangnail, the first thing you should do is try to soften it; cutting a dry hangnail can lead to additional skin tearing and start a vicious hangnail cycle. Begin by soaking your finger or fingers in warm water for a few minutes. Then clip the hangnail with cuticle scissors to prevent jagged edges that might tear. After clipping the hangnail, massage some lotion into the nail bed. Continue to do this a few times a day until the hangnail has healed [source: WebMD]. You can also use an antibacterial lotion at the site of the hangnail, and if the hangnail is deep, you might cover it with a bandage until it heals completely.

If you notice that the area around a hangnail has become red, swollen or filled with pus, you probably have an infection. For bacterial paronychia, you can start at home by soaking the area in hot water two or three times a day. If after a few days there is no improvement or the infection has gotten worse, see your doctor -- you may need prescription antibiotics. And in the case of infections that are swollen and pus-filled, your doctor may need to drain the area [source: WebMD]. If you suspect that you have fungal paronychia, consult your doctor immediately. You may need a prescription for anti-fungal medication [source: MedlinePlus].
