Sorry to hear you're having such a problem with poor little Tilly, it's really hard to know what to suggest, normally they do settle after a while in a hospital cage & it's best to just leave them to adjust but it does seem as though the stress is doing Tilly more harm than good so I think it might be better to give the wheel back, maybe just for a short period each evening or whenever he's most active & see if that calms him down, keep an eye on the swelling & sore feet to make sure they don't get any worse & go back to the vet if they do, there's not a lot you can do to prevent infection but if you see any indication of that he may need antibiotics.
Sorry I can't be more help.
