If you have a condition called Peyronie's disease, you have a thickened area under the skin of part of your penis.¹

This thick area changes the way blood flows through your penis. So your penis may bend at that point when you have an erection. It can be painful.

It's different from a more gradual bend in the penis, which is normal.

You're much more likely to have Peyronie's disease if you've had an operation on your penis. It can also happen if you've had an injury in this area.²
