Mouth sores

It's official (well it has been for a few days) he definitely has mouth sores; and a lot of them. I was able to see about 4 on the inside of his lips and one the tip of his tongue. I'm sure they are all over his mouth. We also think that they go pretty far down his GI track because he isn't really swallowing and he coughed up bloody mucous yesterday when we did his mouth care. He is so miserable. I feel so bad for him and all I can do is push the PCA (morphine drip but he is allergic to morphine so it's hydromorphone.)
The burns are more from the radiation. Where they taped the oxygen mask on his face and put the lead stickers his skin couldn't breath while he was having radiation. Luckily it doesn't seem to bother him too much.
They tested him for RSV since he has a runny nose and has had it twice already. It was negative!!! Not that we're out of the woods yet but it was pleasing to hear that. He's had fevers here and there so they sent cultures yesterday. The results aren't back yet.
His white blood cell count is at .1 today so the stem cell transplant worked. It just takes time for it to come back up.
Please keep our little man in your prayers.
