Internal Medicine

Penis pain during an erection is often caused by Peyronie's disease, a condition in which fibrous scar tissue (plaque) forms inside the penis. This scar tissue can lead to painful erections, curvature of the penis, and difficulty with sexual function. Other possible causes include injury, infection, or inflammation, so an accurate assessment is important.

If you're experiencing pain during erections, don't guess or wait it out. Getting clarity early can make a meaningful difference in treatment outcomes and peace of mind. Take a free, instant, online symptom check to better understand what may be causing your symptoms and get personalized guidance on your next steps.

Explanation

Penis pain when erect can often be linked to a condition called Peyronie's disease. This condition is characterized by the development of fibrous scar tissue inside the penis, leading to curved, painful erections.

Key Points:

  1. Scar Tissue: The buildup of scar tissue in the penis can cause it to bend or curve during erections, which can be painful.
  2. Symptoms: Apart from pain, symptoms include a noticeable bend in the penis, lumps or hard areas, and erectile dysfunction.
  3. Causes: The exact cause is not fully understood, but it may be related to injury or genetic factors.

Management:

  • Conservative Options: There are non-surgical treatments available, including medications and other techniques, aimed at reducing pain and curvature.
  • Consultation: It is important to consult a healthcare provider for an appropriate diagnosis and treatment plan.

Peyronie's disease can affect quality of life, but there are ways to manage the symptoms effectively.
