Yikes! I did something like that in July... I was on a camping trip with metal detector of course and on the first night there, I was trying to break a big rotten log from the bush in the dark to throw in the fire and as I stomped down hard on it, there was a sharp stem on the log where my foot slammed down and it went right through my flip flop and deep into my foot. It went in quite deep, basically had a hole in my foot now and the first thing I thought was..now I can’t metal detect in the water, never mind I couldn’t even walk on it. No way was I gonna let this keep me from detecting in the water. Next morning I put a thick layer of ozanol on and in the hole of my foot, got the wifey to drive to town for water proof bandages and away I went limping to the beach and in the water I went. I detected for 3 days limping in the water with a hole in my foot, never got infected and healed up in a week. Ozanol will save your life, I always keep in my truck. Hope you heal up fast.
