Differential Diagnosis for Penile Burning Sensation after Intercourse
Single Most Likely Diagnosis
- Urethritis: This is the most likely diagnosis, as the burning sensation after intercourse is a common symptom of urethritis, which is an inflammation of the urethra. This can be caused by a bacterial or viral infection, and the lack of rash or discharge does not rule out this diagnosis.
Other Likely Diagnoses
- Post-coital urethral syndrome: This condition is characterized by a burning sensation in the urethra after intercourse, and is often related to urethral irritation or inflammation.
- Prostatitis: Inflammation of the prostate gland can cause a burning sensation in the penis, especially after intercourse.
- Yeast infection: Although less common in men, a yeast infection can cause a burning sensation on the penis, especially after intercourse.
Do Not Miss Diagnoses
- Herpes simplex virus (HSV): Although the patient reports no rash, it is possible for HSV to present with only a burning sensation, especially in the early stages of infection. Missing this diagnosis could lead to delayed treatment and increased risk of transmission.
- Gonorrhea: This bacterial infection can cause a burning sensation during urination, and can be asymptomatic in some cases. Missing this diagnosis could lead to untreated infection and potential complications.
- Syphilis: This bacterial infection can cause a range of symptoms, including a burning sensation during urination. Missing this diagnosis could lead to delayed treatment and increased risk of transmission.
Rare Diagnoses
- Lichen planus: This is a rare skin condition that can cause a burning sensation on the penis, although it is often accompanied by a rash.
- Peyronie's disease: This condition is characterized by a curvature of the penis, and can cause a burning sensation during intercourse.
- Neurogenic causes: Certain neurological conditions, such as multiple sclerosis or peripheral neuropathy, can cause a burning sensation in the penis. However, these conditions are rare and would typically be accompanied by other symptoms.
