Hi, I have gone through your medical history carefully and understood your concerns. A photograph of the affected skin is required to analyze it further before running into final conclusions. From what you describing, it might be athlete s foot or tinea pedis, a fungal infection of the skin. The pus you see coming out is due to bacterial co-infection caused by scratching. I advise to: - keep a good foot hygiene - wash with warm water and soap, pay special attention to skin folds like between the fingers - rinse well with water - dry it well - then, apply Gentian violet solution locally. Let it dry - after that, apply OTC terbinafin and hydrocortisone cream. Or can mix terbinafin cream with diprogenta cream (which contains betamethasone). If no improvement within the first couple of weeks, should consult with dermatologist for a more specific advice. Hope it was of help! Dr.Albana
