Gangrene and salt

they infected my foot with verucas in verucas believe it or not. There is  a centre meter and a half size wound on the bottom of my foot basically. They cut it with an unwashed knife that has been used to abuse a lot of people a few days ago. My wound went black, I think that’s gangerene. The NHS ignore me so I tried doing something myself...I bathed my foot in ultra salty water (5-10% salt). I ground the salt into the wound a bit for good measure. It worked! The black hasn’t come back. I thought I’d let doctors out there know. It could save lives. Damion
