Josh and orbital cellulitis

If you want to know why I am kind of non-existent these days, it started with Eddie being sick for 2 weeks, and then the last 2 weeks have been my poor little Joshy-boy.
This is more miserable than it looks. We are going on 5 days of antibiotics, and he still wakes up and screams in pain throughout the night. I feel like a mom of a newborn again. Most of all, I HATE how sick he is, he weighs about 8 lbs more than Eddie, he looks like a walking skeleton. He is so weak and in pain.
I'm taking him in tomorrow again, this stuff can lead to a lot of yucky issues and it worries me that it has not gone away yet. I hope it's not at a serious level, cause sometimes it requires surgery, and can cause blindness and brain infections. Oh joy.
I'm sure it will all work out eventually, I just feel really sad for him. He is such a sweetheart, and keeps apologizing for waking me up at night, (I have been sleeping on the couch next to him for 5 days), and asking me to go up and down the stairs to get him stuff. (he hardly walks because it hurts too much, so I carry him everywhere) I keep telling him I will do anything he wants, I love him so much. He can't get any sweeter! Poor Joshy.
