My Nurse Practioner Said I Have Monocytosis And She Didn’t

My nurse practioner said I have monocytosis and she didn’t know why but blood test showed viral; therefore she said antibiotics would not help. I have felt bad for at least three or more weeks. Should I go to another doc and get further testing? Can I find out why I have this? Is there anything to help condition? About six months ago diagnosed with asthma. Using Breo
