Ok, which happened first, the ears or the leg? I'd bug my MD until he gave me some real answers! If it's systemic, I would thing it's from the scrape and not the removal of the staples.
Something else I'm confused by is that you're anemic AND your white cell count is low??

My white cell count is low due to my kidneys being "fatty" but my throid was low eons ago. Take synthroid for it. Sounds to me like you have several things going on, Hun, but I'm just talking from personal experience.
Celulitis is
nothing to mess with! It's extremely painful and difficult to get rid of! Wish they had cleaned mine out but NO! I had to let it go away on it's own until it came through the skin. UGH! Then I had an extra powerful antibiotic ointment to put on it. My Dr at the time said the tube cost over $100 so she just gave me some from the clinic.
Like I said, keep after you main Dr until he gives you some straight answers! In the meantime, "allow" yourself all the rest you need and SCREW your boss! LOL
