Day 4 Post Surgery

I had surgery on Monday 10/22 and so far all is going well. Feel better and better each day. Had a lot of gas but that is getting better as well. I do have a question. On the incision where they put the port is the most sore which I was told was normal. But it does have a red brown lost bruise around I hat is size of baseball. I do not think it is infected since I have no fever not hot to touch and nothing coming out of it. Was wondering if anyone else had something similar after their surgery...
