Can Hepatitis C, which I have had for 35 years, cause lumps in the palm of the hand?
Yes and no.
Yes, there is some evidence that suggest a statistical association between liver disease such as hepatitis and Dupuytren’s contracture, which as you know is associated with palm lumps and bumps. But, not all people who have liver disease develop Dupuytrens, and not all people with Dupuytrens have liver disease, but some studies show a tendency for those with Dupuytrens to have a higher than average occurrence of liver problems for reasons that have not been clearly defined.
No, hepatitis C dos not cause palm lumps. TRH
