Itching, Redness, and Odor
Fungal diseases can cause itching, burning, or swelling. Some conditions such as athlete's foot may even cause blistering.
Redness, cracking, chafing, and peeling may indicate a skin-related fungal infection. The affected hair or skin can also become brittle.
An abnormal odor may also accompany a fungal infection. Because fungus multiplies and feeds off of sweat, it can produce a foul scent.
