Hello doctor,

Thank you for the reply.

There are no other symptoms at all, as you asked. I am currently on C-Tax medication and an antibiotic.

Hello,

Welcome back to icliniq.com.

You are suffering from longitudinal melanonychia, which has numerous causes. In your case, it might be due to decreased vitamin D, a thyroid disorder, or raised liver enzymes. I would advise addressing these through proper medication, and the condition should subside in a few weeks.

I hope you are satisfied with my answer.

For further queries, you can consult me at iCliniq.

Thank you.
