I have been ill for the last week with various symptoms - running/blocked nose, increasingly sore throat, fatigue, skin hypersensitivity, fever, night sweats. I had a blood test yesterday and the doctor said i had low white cells (neutrophils) possibly secondary to taking lymecycline, but also an iron deficiency. He said its a viral issue so to have a low threshold for if i get any worse and i feel quite a bit worse today. Are there any symptoms in particular that i should be worried about?
