bunion surgery

hello, i got my stitches removed today and it hurt so much. I almost passed out! My foot is very much still swollen and Im still afraid to get it wet. My doctor have me this flimsy foamy splint to wear at night and it caused one of the smaller wounds to bleed a bit so I removed it. I feel like its an infection waiting to happen. Did anyone experience this? Also what did you use to clean the area? Just warm water?
