When i had foot surgery a few years back here's what i did. I'd clean the area really good -then put on a thick later of polysporin. Next came the gauze (get the kinds that won't stick to the wound!!)
(the bandages i used were similar to the last two on the bottom of this page http://solutions.3m.com/wps/portal/3...esiveBandages/
- i think the ones i got were actually "band-aid" ones but i don't remember. they were water proof, quite large, and VERY adhesive (good for the bottom of feet!).) keep in mind the entire bottom of my left foot was cut open and that area was not one they could stitch up so i had a huge open wound for months- same on my left food but not as bad.
Then i'd take some soft take (the kind that adheres to the tape itself but won't hurt your skin and wrap that well around the site. Next, i put on socks on top of that to keep everything out of the site that might make it worse. (I had two boot casts on at the same time- so i put on one layer of plain white socks then some really thick socks over that) - it REALLY helped!!! Also- ask your doctor about taking Z-pac or other antibiotics as a preventative so it won't get infected!
I hope your foot feels better soon!! Keep the site REALLY clean!
