The air cell should be drawn down by now. Especially if it’s day 31. Are you positive of that? I’ve lost count many times, so I don’t mean that to sound rude.
I personally would try to pick a piece of shell off near the bruise. If your temps have been low (which is probably the case if day 31 is accurate) and try to locate the bill.
Your overall goal would be to get the bill in clear air, including the nostril holes. But avoid any blood or excess fluid if it’s gooey inside. If it is, you can gently use a quick-tip to help clear it away.
