Treatment will depend on your symptoms, your age, and your general health. It will also depend on how severe the condition is. In most cases, the bumps will heal without treatment over 2 to 12 months. In rare cases, they last 3 to 5 years. You may have treatment such as: Removal of the bumps. Your healthcare provider may do this by freezing them (cryotherapy), or using a small blade, a curette, electric sparks, or lasers. Medicine on the skin. This may help the bumps clear up more quickly. Blistering medicines or medicine that helps stimulate the immune system may help. Talk with your healthcare providers about the risks, benefits, and possible side effects of all treatments.
