question: I have a rare staph infection (sensitive to penicillin, which I am allergic to).  I have been on other meds for 2 months and it won't go away.  In the mean time, my blood tests have been crazy.  My MCV is 104.6, MCH 36.1 and I have reactive lymphocytes in my blood. Other blood levels are elevated and some are low.  My WBC is 6.4 and my RBC is 3.67.  Any idea what is going on?
