What are the symptoms of athlete's foot?

The infection often starts between the toes, where skin may become pale, soft, damp, and cracked. Itching or burning can be strongest after removing shoes or socks. Another pattern causes dry scaling across the soles and sides of the feet, while a blistering pattern produces small itchy vesicles. The skin can split and become sore, and the rash may extend beyond the first affected space. Fungal infection may also involve a toenail, which can become thickened, discoloured, or crumbly. Sweaty, enclosed footwear can keep the skin moist and encourage persistence.

Keep the feet clean and dry, especially between the toes, and change damp socks promptly. Let shoes air and avoid sharing towels, socks, or footwear. Do not scratch or peel the skin, as small breaks can invite bacterial infection. A pharmacist or clinician can advise on topical antifungal treatment and whether the nails or another condition also need attention. Continue treatment for the recommended course even if itching eases early.

Seek medical advice if the rash is spreading, recurring, very painful, or not improving with appropriate antifungal care. Get prompt help for rapidly increasing redness, warmth, swelling, pus, fever, or red streaks, which can indicate cellulitis or another bacterial skin infection. A deep crack, marked swelling, or extensive blistering also warrants assessment, particularly if you have reduced sensation or a condition affecting circulation.

Does this pattern fit athlete's foot or another cause of foot itching? Should my toenails be checked for nail fungus? Which topical antifungal treatment should I use, and how can I prevent the rash returning?
