testosterone can cause pain at the injection site and other symptoms but it's not injected into the penis. peyronie's disease is a condition that leads to deformities of the shaft of the penis. a curved penis or lumps/nodules along the shaft is often what is seen on exam. and so you may want to see your urologist. it's more common that you think. men who don't engage in sex may not realize that the deformities/lumps exist since this is often not seen in a flaccid penis. in some men this condition can cause pain difficulty with sex and erectile dysfunction. while genetics and trauma have some association to peyronie's disease the exact cause of this condition is not known. there are medications to treat the symptoms associated with the condition. these include medications or surgery in severe cases.
