What causes petechia and headaches no fever? Wbc 7.1, gran 5.0, % 71, mono&lymph2.1, mono&lymph% 29% platelets 383, hematocrit 39.2. Is lymph % high?

Your note is confusi. You need to carefully separate these numbers. The way you ahve written is totally unclear. Use a dash to connact each cell with %. It looks like your gran % is 5% , which would be quite abnormal...They should be over 40%(normally 50-70%, rest are supposed to be lymphocytes. Also give us your hemoglobin and platelet counts.
