I have recently had 2 blood tests and both have come back with a low white blood cell count.  I had the swine flu a couple years ago; could that be the reason?  Im also pretty tired lately which is one reason I went to the doctor.  Other symptoms are typical menopausal symtems and tingling in my feet and legs.
Many cause of low WBC counts are there. Simple viral infection may lead to low WBC count. However, its unlikely that its due to swine flu two year back. You may have some unnoticed infection and DUS to that your WBC count may be low. But if you don't SVD any other problem then it's ok. If you had sever low WBC count and had some problems then only go to physician and take treatment as per advised. Otherwise, it's not needed.
