Necrosis help/advice needed

My bad if this isn't the right sub for this, but I couldn't find a better spot to dump this 🙂

So, here's the deal. About two weeks ago, I stepped on some glass and ended up with a pretty deep gash on my lower leg. I hit the ER a day later—yeah, yeah, I know I should've gone immediately—and they told me everything looked fine. They just said to wrap it up with sterile gauze and some medicated mesh so it wouldn't dry out (picked that stuff up at a CVS).
The cut itself wasn't even the main issue; it was this tiny little bit of flesh (maybe a square centimeter?) that I’d basically "trimmed" because it looked a bit darker than the rest.
I've been seeing a doctor to get it dressed, and she's been cleaning it with hydroxide, peroxide, whatever—it gets all white and foamy—plus some spray and Betadine. Since I'm finishing up my vet tech studies and know a thing or two about medicine, I kept asking her if that little dark patch was actually "alive" or if it was dead tissue.
Every single time, she gave me the same line: everything's fine, it's just some bruising under the skin, no biggie.
Then I show up today, and suddenly it's "necrosis." That's it. Just like that. She wrapped it back up and told me I need to come back Tuesday...

So now I'm wondering—what's the worst-case scenario here? It's not a massive area, but this whole "necrosis" thing is starting to freak me out a bit xD
Is there any chance this could just spiral out of control? She mentioned we have to wait for healthy tissue to grow back, but she didn't sound exactly thrilled when she said it. In a worst-case scenario, are we talking about just cutting off that tiny bit of skin, or is it something more?

It's definitely weighing on me, so thanks in advance for any insight 🙏

I suspect you might find much more helpful insights over on the Health & Wellness forum.

I’m more than happy to migrate our conversation over there if that works for you.

Sure, sure, but honestly, I wasn't even sure where to put this—it’s really the only thing I could dig up... I don't hang out on this forum all that often, so here we go...
thanks 🙂

People tend to jump straight to thoughts of amputation whenever they hear the word necrosis. In reality, necrosis is just a broad medical term for tissue death. From what I can gather about your situation, you’re looking at a minor wound that doesn't seem to have any potential for serious complications. Just leave it alone—don't touch it—and make sure you show up for all your dressing changes. It’ll heal on its own.

My mom actually went through this recently. She ended up with some skin necrosis too, though she’s always struggled with poor circulation in that leg anyway. It all started when she bumped her leg against the edge of a bench and got this tiny little scratch. At first, it didn't look like much, but then the skin around the edges turned bright red and became incredibly inflamed. Her surgeon told us to apply Betadine to some gauze. So now, in the mornings, I apply the Betadine on gauze and secure it with some Micropore tape. In the evenings, I just leave a sterile gauze pad on it. Honestly, the wound looks so much better now; we’re basically just waiting for the scab to fall off. She hasn't been going in for professional dressing changes—I just handle everything for her at home. She only went back to see the surgeon a few times for checkups.
