Can I have a vacation day from being sick?

It's now been over a week since I first got sick.  My foot was so swollen, I could barely put my largest shoe on it.  The cellulitus felt like it was at stand-off with the meds, so I went back to the doctor yesterday.  She agreed it wasn't going well.  As a precaution, she sent me for a sonogram to rule out a blood clot in the leg.  That was fine, so she changed my antibiotic.  Day one on new med and it looks a little less red - it's still as sore, esp. when I go from laying down to standing.  I'm off work until next Monday, when I really hope all will be well enough to go back.  I'm using 7 full sick days for this stupid stuff. 

Well, I've been up long enough - back to bed with me, myself and the red, swollen leg - thank goodness we have a king size bed!
