What is a typical symptom of Hepatitis C infection as presented in a clinical case?

A typical symptom of Hepatitis C infection is dark colored urine. This occurs due to the liver's impaired ability to process bilirubin, a byproduct of red blood cell breakdown. In cases of hepatitis, especially viral hepatitis like Hepatitis C, liver inflammation can lead to the accumulation of bilirubin in the bloodstream, which then gets excreted in urine, resulting in a dark brown or tea-colored appearance.

In contrast, the other symptoms listed, such as coughing and wheezing, joint pain and swelling, and nasal congestion, are generally not associated with Hepatitis C specifically. Coughing and wheezing may suggest respiratory issues, while joint pain can arise from various conditions but is not a hallmark symptom of Hepatitis C. Nasal congestion typically points towards upper respiratory conditions, making them less relevant to the clinical presentation of Hepatitis C. Thus, dark colored urine serves as an important indicator of the liver's dysfunction in this infection.
