It's not nerve damage that prevents normal healing, it's the damage to blood vessels - but that should not be present if you have good control (i.e. even if you had it, it's easily reversible). Nerve damage is also reversible, but can take a long time, and the danger is that because of it you won't feel a problem on your foot (a cut, scrape, blister), so it can flare up and become much worse before you realise what's going on.
So you should be healing just fine!
Just keep taking good care of it, and your BG levels. Hope you're better soon!
