The first symptom is usually a small painless bump that looks as if it is an insect bite. It can be red, pink, or purple in color. The bump usually appears on the finger, hand, or arm where the fungus first enters through a cut in the skin. This is followed by one or more additional bumps which resembles a boil. Eventually lesions look like open sores and are very slow to heal. The infection can spread to other areas of the body as well. In more serious cases the fungus follows lymph nodes in the body, causing small ulcers to appear on the skin as the infection goes up an arm or leg. These lesions do not heal unless treated and may remain ulcerated for years. If the infection affects the entire body it can cause lung and breathing problems, bone infection, arthritis, and infection of the nervous system. The first bump may appear any time from one to twelve weeks after your skin has been exposed to the fungus. Usually the bumps are visible within three weeks after the fungus enters the skin.
