About half of men with Peyronie's disease will first notice pain during intercourse. Symptoms may appear suddenly, or may develop slowly over time. Often the penis will feel firm or lumpy at the painful site.
Other men with Peyronie's will notice a painless curve of the penis that can occur suddenly or get worse over time. The penis may curve up, down or to either side. Severe changes in the shape of the penis may prevent the man from having intercourse.
If the penis has been injured by sudden trauma, most men will be able to recall the event. Often there will be a sensation or sound of a "snap" followed by loss of erection and the appearance of a bruise. Part of the penis will remain painful for a time. But usually the area will heal over time. However, scar tissue may form and cause a new curvature. This problem is different from Peyronie's. It rarely results in difficulties with erections or shortening of the penis.
