Several treatment options are available when it comes to how to get rid of blood blisters on scrotum. In fact, they usually do heal even without treatment.

What causes blood blisters on the scrotum?

As to what causes blood blisters on scrotum, any of the following can be responsible:

Angiokeratoma scrotum

This is a condition that causes red or purple bumps on the scrotum. At first, invisible bumps will be felt on upon touch. If scratched, they will bleed. The blisters turn dark red in a day.


Herpes is a viral disease. The type that affects the genitals is likely to cause red bumps on the scrotal sac. Oral herpes may cause blood blister under tongue and in the mouth. It is thought to be the most common STD in the world. While sexual intercourse is its main transmission mode, skin to skin contact with an infected person can transmit the herpes virus.

Prostate enlargement

A benign form of the condition that causes the prostate to enlarge more than normal can be the cause of blood blisters on the scrotum. It is mostly reported in men over 50 years of age. Other than the blood blisters, a lump will also be noted above the scrotum.


This is a type of acne of the scrotum. It forms when hair strands get trapped in the follicles. Due to infection by bacteria or virus, red bumps will form.

Other health conditions

  • Quite a number of health conditions can result in blood blisters on scrotum. They include:
  • Venous hypertension – causes high blood pressure on body parts nearer to the ground.
  • Varicocele – causes the blood vessels in the scrotum to enlarge.
  • Chicken pox and shingles – causes an itchy rash all over the body.

Other causes

Deficiency in vitamins B12 and C might be the cause. Such a deficiency will also cause a blood blister on the roof of the mouth. Low platelets count in the blood makes it hard for blood to clot, hence encouraging blood blisters under the skin. Allergic reactions, heat and cold may damage skin tissue and cause blood blisters.

Treatment for blood blisters on the scrotum

Often enough, blood blisters on the scrotal sac will go away on their own. However, medical treatment is necessary if the blisters become painful. You may also notice a lump on or near the scrotum. In that case, it is best that you see your doctor.

Other signs that a doctor should address include symptoms such as fever, fatigue, pus formation, recurrent blood blisters and persistent itch.

If you experience blood blisters that keep bleeding, it may be that you are having a low platelet count. This is a serious condition which should be checked by a doctor.

Normal blood blisters mostly require medical treatment if they get infected. Signs of infection include swelling, pain, pus, red streaks and fever. Your doctor will prescribe antibiotics and maybe some painkillers.

Depending on the cause, further medical treatments will be prescribed to address the root cause of the blood blisters.
