If athlete's foot goes untreated, it can cause a number of unpleasant and painful symptoms. The infection can spread to other parts of the body, such as the nails, scalp, and even the groin area. This can cause itching and burning sensations, redness, and scaling of the skin. Eventually, if left untreated, athlete's foot can cause blisters, open sores, and even ulcers.
In addition, you may be more likely to develop bacterial infections, such as cellulitis, which can cause swelling and tenderness of the skin. Fungal infections can also spread to other parts of the body, such as the eyes and mouth, and can even cause blindness.
If the infection is not treated, the risk of complications and other health problems increases. People with compromised immune systems, such as those with HIV, are more prone to developing serious complications from athlete's foot.
Therefore, if you suspect that you have athlete's foot, it is important to seek medical attention and begin treatment as soon as possible. Treatment usually includes antifungal creams or ointments and keeping the feet clean and dry. If the infection does not respond to treatment, your doctor may prescribe oral antifungal medications.
