I've got these medicated sponges that I'm supposed to wash with before the surgery. Last night, I tried one out, and it went okay, although my feet started feeling uncomfortable shortly after. Well, now, I have itchy blisters on my legs and feet, but some of the sores on my arms and neck (my skin is shit) dried right up. So, yeah. I'm going to use the other pad to wash before I leave for the surgery, but I'm not thrilled with the results.
