Rash on middle finger. About once a week it gets intensely itchy, to the point where I scratch so much it bleeds bigly and pieces of skin come off. The scratching produces a feeling of relief. The itchiness is brief but intense, leaving a yucky skinned and gouged mess which stings somewhat (worse under hot water).Then it heals over the next couple of days, and after about a week the cycle starts again.
It has not responded to Miconazole, Clomazol or any other anti-fungal.
What is this and how do I fix this?
