Wound bleeding

Hi everyone, hope you're doing well. I'm Bibs, 48 and Stage 4 bowel cancer.

So I had my liver/gall bladder resection a week ago (mets from bowel) and had been doing well but the past couple of days my scar felt very red, sore and a lump started to appear on one side. The surgeon wasn't concerned at first and I was due to go home today but last night he took a look and decided it needed further exploration. He said he would come and potentially put a small cut in the lump to see if fluid comes out etc. Anyway, between him coming last night and today I started bleeding from the wound. I went to the toilet and noticed I was dripping blood onto the floor. I could easily isolate where it was coming from and the nurse put a plaster over it but it's saturated in blood this morning. (Don't get me wrong, it's not pouring out of me, but clearly there's a bit of an issue there.) The nurses want to leave me with a bloody dressing, blood on my nightdress/bed sheets etc so the doctor can see it at it's worst when he does his rounds. Problem is that no one seems to know when the rounds might me and I feel concerned. Has anyone had 'pockets of blood' after an op or similar? Does this indicated infection? My GP is a bit low (but usually is) but other stats/blood tests feel fine so no one seems unduly worried but I feel like they've written me off as I'm last week's news! Any advice gratefully received. Thank you :) x
