Bumblefoot?

[HarrytheHammyx]

Soo I have this Syrian hamster and his name is Squishy. Recently I noticed a big bump under his foot and when I searched it up, it said he has bumblefoot. Apparently it happens when you have a mesh wheel and I was guilty of having one so when i realized I patched it up so the mesh was covered perfectly. Thing is I'm not sure so here are some pictures. Can someone help me pleasssee? The pictures look kind of painful so I suggest if you're queasy you shouldn't look at them. And if it is bumblefoot can someone help give me remedies (preferably natural ones with things you find in your house) so I can treat him right away (as well as medication.) He doesn't seem so disturbed by it though, he still runs the whole night and loves eating sleeping cuddling. Don't worry bout the pic where I'm holding him, he woke up from a nap and he doesn't mind being held like that, I'm grasping him very lightly!
