Well, StlWalnut had to spend another night in the Springfield Hotel. It seems the staff is concerned about a small pneumothorax in the right side of his pleural cavity - this is a kind of bubble where his lung has separated a little bit from the chest wall. The only treatment for it is to monitor it with periodic x-rays to make sure it doesn't grow into a full-on collapsed lung.
StlWalnut and his family are hopeful that his x-ray this morning will be good enough to allow his release.
