I Apply Antifungal Cream And Powder Daily Also Triple Antibiotic

I apply antifungal cream and powder daily also triple antibiotic when the blisters pop but nothing seems to give. When they pop the blisters fill up with more fluid and then more blisters appear. One blister popped and as I lifted up the skin to see inside it was like a deep cutt. I cant afford to go to the doctors to go for lab tests, I cant take this issue happening for Im affraid it could spread let alone give it to my children or spouse. I need help and advice of what to use and or do.
