Training I can do while my shin has Cellulitis?

Ok I do MMA but while doing a Kickboxing session during the month I contracted Cellulitis in my shin so it stings like **** and I can't kick any pads or bags for a while also I can't Roll in BJJ either as I'd have weight put on my shin and it would be extremely painful , so what can I do to try and ward of stagnation so I don't completely burn out when I come back to training should I just Shadowbox and do upperbody weight training? I can run but not for to long before pain sets in
