Differential Diagnosis for a 26-year-old Male with Painful Tip of Penis, Bladder Pain, and Abdominal Pain
- Single Most Likely Diagnosis
- Urinary Tract Infection (UTI): This is a common condition that can cause bladder pain, abdominal pain, and painful urination, which might be perceived as pain at the tip of the penis. The symptoms presented are consistent with a lower urinary tract infection.
- Other Likely Diagnoses
- Prostatitis: Inflammation of the prostate gland can cause pain in the abdomen, bladder, and genital area, including the tip of the penis. It's a common condition in young men.
- Urethritis: Inflammation of the urethra, often due to infection, can cause painful urination and discomfort at the tip of the penis, along with possible abdominal pain if the infection spreads.
- Epididymitis: Inflammation of the epididymis, a tube at the back of the testicle that stores and carries sperm, can cause pain in the testicles, abdomen, and potentially radiate to the penis.
- Do Not Miss Diagnoses
- Testicular Torsion: Although less likely given the specific symptoms, testicular torsion is a medical emergency that can cause severe pain and needs immediate attention. It's less common but critical not to miss.
- Appendicitis: While the primary symptom of appendicitis is abdominal pain, in some cases, the pain can be referred or accompanied by urinary symptoms if the appendix is located near the bladder or ureter.
- Kidney Stones: Small stones can cause severe pain as they move through the urinary tract, potentially causing bladder pain, abdominal pain, and pain that might be felt at the tip of the penis during urination.
- Rare Diagnoses
- Reiter's Syndrome (Reactive Arthritis): A rare condition that can occur after certain bacterial infections, leading to symptoms including urethritis, conjunctivitis, and arthritis, which might explain some of the symptoms.
- Interstitial Cystitis: A chronic condition causing bladder pressure, bladder pain, and sometimes pelvic pain, which could be considered if other diagnoses are ruled out and symptoms persist.
