What causes cracked, oozing, and painful skin between the toes, and what should be done about it?

Watery discharge and pain between the toes may be caused by trauma, eczema, athlete's foot (tinea pedis), paronychia, diabetes, or other conditions. Different treatments should be selected based on the specific underlying cause. The details are as follows:

1. Trauma

If the skin between the toes is injured and the wound is not properly treated, bacterial infection may develop, leading to pus discharge and pain at the site. Under medical guidance, patients can use hydrogen peroxide solution, povidone-iodine solution, or normal saline to clean and disinfect the affected area.

2. Eczema

Eczema is a chronic inflammatory skin condition. When it occurs between the toes, it may result in oozing of fluid and pain, presenting symptoms as described above. Patients may use medications such as hydrocortisone butyrate cream, triamcinolone-miconazole-nystatin cream, or sulfur ointment as directed by a physician.

3. Athlete's Foot (Tinea Pedis)

Athlete's foot is a fungal infection of the feet caused by dermatophytes, commonly occurring between the toes and on the soles. It may lead to local blisters, pain, maceration, oozing, or ulceration between the toes. Under medical supervision, patients may apply urea vitamin E cream, compound clotrimazole cream, or miconazole nitrate cream for treatment.

4. Paronychia

Causes include prolonged exposure to irritants or excessive nail trimming, which allow bacteria to invade the surrounding tissue, resulting in pus formation along with swelling and pain. Treatment requires topical antibiotics such as erythromycin ointment or fusidic acid sodium ointment as prescribed by a doctor.

5. Diabetes

In individuals with diabetes, increased blood viscosity can impair circulation, leading to nerve dysfunction and vascular occlusion—commonly affecting the toes. This may result in local swelling, ulceration, and the aforementioned symptoms. Patients should follow medical advice and take medications such as metformin hydrochloride sustained-release tablets, cefuroxime axetil tablets, or cefaclor dispersible tablets.

In summary, if any of the above symptoms occur, patients are advised to seek prompt medical attention at a hospital for accurate diagnosis and standardized treatment.
