Hi, I went into the er last night with neck pain , migraine , sore throat , fatigue , weakness, and shortness of breath. I had a breathing treatment, chest xray, and blood work done. All came back normal except my monocyte levels were high. But my mono test was negative. They discharged me with a prescription for cough syrup and a diagnosis of viral infection. Here is my question. First, am I contagious? And second, should I follow up with my GP? I am a 25 year old female.
