I had a cyst on my kidney removed last monday, it was laparoscopic so not much of a wound, three little incisions. All seemed to be healing ok, I followed all advice for wound care, but one of the incisions seems to be more painful today and it's hot and hard. There's nothing oozing, it's all dry, but it is sore, so I was wondering if there's likely to be an infection inside. My mum says it's hot and hard because there's scar tissue underneath, but something doesn't feel right about it. The other wounds are completely different, not hard or hot in any way. Should I try and see the nurse practitioner for some antibiotics? I was given some post op, and I'm not usually keen on taking them unless it's absolutely necessary but my mum nearly died of sepsis earlier this year and I'm utterly paranoid now.
