Hi sir/mam, My mother is having some sort of infection on fingers of hand, she is seeing certain cuts on them and itching also on hands. So it becomes dry and then cuts appear on fingers. We consulted one doctor over call and they said it might be allergy due to onion, ginger or garlic. Can you please suggest if some ointment to apply or reason of this allergy. I have added picture as well.Thanks in advance.
