Okay so I went to see a doctor and after examining me she noticed the lump I've had for 2 weeks now on the left side of my neck above my collarbone was quite big so she ordered a blood test for me and an urgent ultrasound scan. I am still waiting for an appointment to be made for the ultrasound but I did my blood test and got a call from my doctor this morning saying my results came back abnormal, with a high WBC count of 17,200 and and elevated neutrophils, platelets, ESR, CRP and LDH.

She said it might be a bacterial infection and wants me to repeat the blood test. Problem is I have no symptoms of infection, no fever, pain, cough, nothing. Could it be something more serious than an infection given that I have no symptoms?
