### Patient: Doctor, I have been feeling nauseous and have lower abdominal pain. Additionally, I have been feeling weak in my lower back and have been experiencing pain on my side. What could be the issue?
### Doctor: Based on your symptoms, it is possible that you may be suffering from Urethral Valves. This condition is characterized by the narrowing of the urethra due to the presence of abnormal mucosal folds, which can cause a blockage in the urinary flow and thus, result in symptoms such as nausea, abdominal pain, and weakness in the lower back. I advice you to consult a specialist in this field as soon as possible.
