Penis injury, swelling or pain

It is normal for the penis to swell with blood during sexual arousal to form an erection. But sometimes the soft tissues in the penis can get swollen and painful due to an injury.

The skin on the foreskin and scrotum is very sensitive and can get swollen, inflamed and painful after an injury.

Blood at the tip of your penis or in your urine (pee) is a sign of a serious injury. If you are worried about penis swelling or pain, see your doctor.

Penile injuries

Injuries to the penis can happen during sexual intercourse (sex), or because of:

• scratches
• bites
• knocks
• burns

You can cause an internal injury if you put an object into your urethra (the tube in your penis that urine and semen come out of).

You can also injure your penis if you put a tight ring or stiff object around it, blocking blood flow.

Skin allergies

Sometimes, creams and lotions can cause a local allergic reaction leading to painful swelling.

Penile fracture

You can fracture (break) your penis if there is too much force on it while it's erect, such as during sex or when masturbating. You might hear a crack or a pop. Since there is no bone in the penis, it can't break in the same way a leg can. However, the soft tissue in the penis can tear, causing bruising and pain. A fractured penis needs urgent surgery, preferably within 6 hours of the fracture.

Peyronie's disease

The penis can also become hard and swollen if you have Peyronie's disease (Opens in new tab). This condition can cause the penis to be painful, bent or less flexible. Speak to your doctor if you have Peyronie's disease and you have pain in your penis.

Here are some tips to help if you hurt your penis:

• Minor bleeding — Apply direct pressure to the site for at least 10 minutes using your fingertips and a cloth, gauze or dressing.
• Swelling — Use an ice pack to help ease swelling, but don't place it directly on your skin. Wrap a bag of frozen peas in a cloth and mould this around the swollen area.
• Foreign object —If there is anything tight around your penis or scrotum, remove this right away — if you can without injuring yourself.
• Cuts or grazes — Cover with a clean, dry dressing or thin cotton cloth.
• Burns — Loosely cover the area with clean cling film (plastic kitchen wrap). This is a good option as a dressing for burns.
• Pain — Wear close-fitting underpants to give support to the painful area.

If you are in pain, ask your doctor or pharmacist for advice on medicines you can take.

You should see your doctor if:

• your penis is very red and swollen or very bruised
• it hurts to pee
• there is a discharge or pus coming your penis
• you have severe pain in your genital area

Protect the area as much as possible to stop further damage or injury when going to see your doctor or to hospital.
