I have had general illness for about 10 weeks on and off: chest infections, runny nose, sore throat, lethargy, painful and enlarged lymph nodes. My Dr sent me to a haematologist 3 days ago. My bloods were normal and he said it's just probably many viruses on top of each other and my immunity is low. I work with young children and experienced a lot of work stress just before I got sick. My white blood cell count was 4.4. I understand this is at the low end of normal. Since yesterday my chest pain has increased upon exertion and I'm just so tired. I just keep getting sick! My armpits hurt due to the enlarged nodes. The Haem said he felt 2 x 1cm enlargements. Should I keep an eye on the WBC and go back to my Dr if I'm not ok in 2 weeks?
