What to do if i shaved my pubic hair and now i have large bumps and its extremely itchy! help?

Ingrown Hair: Often an ingrown hair will go away on its own. If it doesn't go away, an ingrown hair can become infected, permanently darken the skin, or leave behind a scar, especially if you've been scratching or picking at it. If an ingrown hair is bothering you or has become infected, your doctor can make a small cut in your skin with a sterile needle or scalpel to release it or prescribe medicine.
