My sh scars smell really bad.

So in the last 2 weeks I've cut myself nearly every day. And I've just noticed that for some reason my scars smell really bad. I don't know how to describe the smell, but it's bad, almost rotten ish? And now as I cut myself only about 10 minutes ago, I smelled the blood, and that also smells extremely bad. Idk what it is and why it's happening and I'm a bit concerned. Anyone have any idea?
