Why does the penis swell and hurt when it gets hard?

The male penis is a very important male reproductive organ, and there are abundant blood vessels and spongy tissue in the male reproductive organ. If there is damage, inflammation and other problems, pain symptoms will appear immediately. In more serious cases, it will continue to affect the male sexual function. Therefore, if men have symptoms such as pain when the penis is erect, they should pay attention to it and should promptly carry out targeted treatment according to the cause of their own disease.

Why does the male penis become painful when it is erect?

1. Local inflammation: If a man's penis hurts when it is erect, it is mostly caused by local inflammation. For example, when urethritis occurs, different degrees of penis erection pain symptoms will immediately appear. Especially when a man has gonorrhea or non-gonococcal urethritis, there will be obvious infection symptoms in the urethra of the male genitals. When the penis is erect, the internal tissue will immediately swell, and the injured area will be squeezed and irritated, causing pain symptoms.

2. Penile cancer: If the penis of middle-aged or elderly men is very painful when erect, and there are also relatively prominent tumors on the genitals, you should consider whether it is caused by penile cancer. It is best to see a doctor immediately and ask the doctor to do a diagnosis so that timely measures can be taken to start treatment.

3. The male genitals have suffered trauma: This is also a common cause of pain when a man's penis is erect. For example, some men masturbate more often, which will immediately cause damage to the skin of the male genitals. When the penis is erect, the damaged area will immediately stretch, causing significant pain. Some men's clothes and pants cause friction damage to the skin of the male genitals, which will also cause pain when the penis is erect. At this time, you should pay attention to the painful area carefully. If damage is found, pay attention to disinfection and anti-inflammatory treatment.
