I have a sore under my nail plate on two of my fingers. They’re painful until I drain the pus, then in a few days the sores start hurting again. I think they’ve been misdiagnosed as fungus. Please suggest a treatment.

A sore under the nail plate with pus indicates an infection. The most common type of infection under the nail that produces pus is bacterial rather than fungal. A dermatologist should obtain a sample from underneath the nail for a culture to identify the problem, then recommend the proper treatment. It is not advisable to treat this condition on your own.
