Differential Diagnosis for Penis Pain
- Single most likely diagnosis
- Phimosis or paraphimosis: This condition is characterized by the inability to retract the foreskin (phimosis) or the foreskin getting stuck behind the glans penis (paraphimosis), leading to pain and swelling. It's a common issue that can cause significant discomfort and is often seen in clinical practice.
- Other Likely diagnoses
- Balanitis: An inflammation of the glans penis, often caused by poor hygiene, infections (bacterial, fungal, or viral), or allergic reactions. It presents with pain, redness, and swelling.
- Urinary tract infection (UTI): While more common in women, men can also experience UTIs, which can cause pain in the penis, especially during urination.
- Epididymitis: An inflammation of the epididymis, a tube at the back of the testicle that stores and carries sperm. It can cause pain in the testicles, penis, and groin area.
- Peyronie's disease: A condition characterized by the development of scar tissue inside the penis, leading to curved, painful erections.
- Do Not Miss diagnoses
- Testicular torsion: A medical emergency where the spermatic cord becomes twisted, cutting off the blood supply to the testicle. It can cause severe pain in the testicle and penis and requires immediate attention.
- Penile fracture: A rupture of the tunica albuginea, the fibrous layer surrounding the corpora cavernosa, often occurring during vigorous sexual activity. It's a painful condition that requires prompt medical intervention.
- Penile cancer: Although rare, penile cancer can cause pain, especially if it progresses and invades surrounding tissues.
- Rare diagnoses
- Priapism: A condition where the penis remains erect for hours, causing pain and discomfort. It can be caused by certain medications, medical conditions, or unknown reasons.
- Penile thrombosis: A blood clot in the penis, which can cause pain and swelling. It's a rare condition but can be associated with significant morbidity if not treated promptly.
