I see slightly raised scales in the first picture as well. I don't think hes just bloated either, the swelling is on his body around his dorsal, not his belly.....I'm no expert, but I'd say its a pretty bad bacterial infection.
Wait for a second opinion on this, as I have very little personal experience treating diseases, but I would treat him with a bit of Epsom salt for the swelling and either Maracyn 1+2 or Tetracycline.
