👉 Brachidia is a type of fungal infection that occurs in the skin, usually on the upper part of the leg or foot, and can be caused by several different types of fungi. The fungus that causes brachidia typically lives inside the skin cells, causing inflammation and damage to the surrounding tissues. Symptoms may include redness, swelling, pain, and difficulty walking. Treatment often involves using corticosteroids to reduce inflammation and help heal the infection.
