bbf it might have been perhaps a bit of debris or something from a previous inject, or something like that. im not buying this whole razor thing, as a didnt when i saw your original thread. maybe, but unlikely.
anyway, dont worry about your size, itll come back quickly. i was recently laid up for a good 2 weeks flat on my back with a couple of persistent infections, also on morphine tabs (morphine is GREAT pain relief, i love those little pills...how the hell do people party on them though? woo i was out of it) and anyway, i lost maybe 13lbs in the 2 weeks. gained half of it back in the past week, and lost some bodyfat on top...almost makes it worth it lol
hope for a speedy recovery
