Thinking back, I put a non-stick dressing on it for a long time as it continued to seep. I did the salt water soak followed by peroxide dabbed into the cut, followed by a little lavage (rinse) of sterile saline. Drip dry and then dressing. Two or three times a day for almost a month, then once a day until healed over. Dressing was a couple of pads and taped into place, followed by ace bandage to keep foot together. I was extremely lucky to avoid tendon/ligament damage -- just ridiculously lucky given the size and depth.
That nasty flesh eater ... necrotizing fasciitis (sp?), some member of the streptococcus clan? Initially, they were very worried about some heinous infection from the oysters. Lucky again, I suppose, although as a precaution they gave me some antibiotics that made me sick as a dog if I didn't eat first. A glass around the hot tub should be relatively benign bug-wise, or?
