Antifungal medicines come in three forms. Onychomycosis means fungi in your nails. Fingernails take six months to grow and toenails 18, so treatment must be long. The nail may dissolve or be white or brown. Toenails are infected four times more often than fingernails, particularly in the elderly.
Some fungi make the nail white at the cuticle, others at the growing edge.
New medicines are changing the outlook for this unsightly disease. The sofa, beds, telephones, toys and hairbrushes need cleaning. T. corporis infection occurs on the chest, back, arms, and legs, usually in multiple red rings with small blisters at the edges. Ringworm in children may come from kittens or dogs - see the veterinarian. T. cruris of the crotch is more common in men, sparing the scrotum, but affecting the upper inner thighs, groin, pubic area, and buttocks.
