Please pray!

Hey friends! My Dad was admitted last night to the hospital with an unknown source of infection. He had high fever, generalized malaise and was talking out of his head a bit. They have ruled out all of the yucky things: meningitis, feared flu bugs, pneumonias, even blood clots. There seems to be some emerging cellulitis in his leg that the doctors are treating aggressively. He is responding nicely to the antibiotics. But the redness in his leg continues to increase. So... you praying warriors, get to it!
