Very quick update, as I'm supposed to be not typing or doing any work (just great...great timing...). I went back to the hospital in middle of night last night; was given first round of antibiotics by IV. I will go back at least twice more - every 24 hours - for same. I am meant to be resting the arm, which is hard to do when you're on crutches.
And frankly, life fucking sucks, in more ways than this.
