Itchy, ulcerated toes can be caused by the occurrence of certain skin conditions such as tinea pedis and eczema. Tinea pedis is caused by a fungal infection and mainly manifests as blisters, oozing and erosions on the skin of the foot, which can be accompanied by a pronounced itching sensation; eczema on the foot mainly manifests as red spots and papules, which can be eroded and oozing and can also be accompanied by a strong itching sensation, and some other diseases can also cause similar symptoms.
In case of itchy toes and skin ulcers, prompt consultation with a dermatologist is recommended for an early and definitive diagnosis before targeted treatment can be given.
