I have this skin infection between my two fingers (ring finger and middle finger). It is getting worse and worse. It itches and burns terribly. It is extremely painful. Lots of little blisters keep forming under the skin and then they pop everytime I bend my fingers. The skin over the blisters is so hard, it cracks and bleeds with any little movement. I have tried many ointments, but nothing seems to be working. Funnily enough, though, this infection has not moved to any of my other fingers. Could you suggest some course of action for me to take please.
