Question

About 50% of nail dystrophies result from fungal infection. The remainder result from various causes, including trauma, congenital abnormalities, psoriasis, lichen planus, and occasionally cancer. Diagnosis may be obvious on examination, but often fungal scrapings and culture are done. You can try a variety of home-based methods to treat nail fungus: clean the affected area with soap and water daily. Groom your nails regularly. Apply an over-the-counter fungal treatment after you gently file your nails. Apply vicks vaporub on your toenail each day.
