I had a laparoscopy on 5th Jan where they removed some endometriosis and disconnected my bowel from my left side where adhesion's were connecting them. When I came out of surgery, the incision in my belly button was very sore. I had a cough and every time I coughed, the pain and pressure on my belly button incision was excruciating, much more so than any of the other incision sites. I noticed about 3 days after the op that there appeared to be a hard lump in my belly button that wasn't there before (I've always had a very neat 'innie'. I assumed that this was maybe just a large scab filling my belly button since there had been some bleeding and weeping from the incision but when the scab came off about 13 days after the op, I realised that it appeared to be a lump of flesh in my belly button. I have no feeling on the skin of the lump but it is vaguely uncomfortable when I move or cough or when i wear high waisted jeans. I can't see the incision that was made, it appears to be directly under the lump since I can see stitches poking out on either side of it. After doing some googling, I am concerned that this could be a hernia but I don't have any knowledge in the area, I was wondering if anyone could give me some advice on what this could be? I have attached a picture for reference in case that helps.
Thanks in advance for any responses.
