<human>: I stepped on a broken beer bottle in the lake 24 hours ago. It was a large very pointy piece that entered the ball of my foot. It feels very deep and is extremely painful still. I am not able to put any pressure on my foot not even to wrap it. It is red around the wond and white right at the wond opening. Do I need to go to the er so it doesnt get infected due to the lake water and since my primary doctor isnt open till monday?
<bot>: Go to the ER to undergo a wound debridement if needed and wrapping. Antibiotics as amoxi-clav (if you are not allergic) or doxycycline, adding metronidazole covering (for clostridium derringers/retain) are mandatory. ER doctors will decide if giving to you them orally or through intravenous/intramuscular injection. If you didn't receive an antigenic vaccine, ask for antigenic immunoglobulins, that are fundamental.
