hi.fungal infections are very common in diabetic patients because the immunity is compromised in such patients.if only the surface of nail is involved and the infection is not very deep use only topical antifungals.but if more than one nail is involved and the infection is deep also start oral antifungals.
take tab terbinafine 250mg 1od for 3 weeks.
n terbinafine cream bd for one month I hope it 'll solve ur prob thanks.
