I am sorry to hear about your symptoms, and it sounds like they are affecting your life quite a bit. I encourage you to discuss your low blood count with a hematologist
. It is not possible to provide an accurate explanation for this lab finding without knowing the full details of your medical history, performing a physical exam, and looking at a sample of your blood under a microscope.
White blood cells are cells in your blood that act as part of your immune system. They help target bacteria, viruses, and other sick or dying cells for destruction. Many different conditions can cause a low white cell count. In some cases, a severe bacterial infection can cause a low blood count. Viruses can often cause suppression of your bone marrow, leading to decreased production of white cells as well as other cells in your blood. A viral infection could potentially explain your headache
, as well. In some cases, leukemia, which is a type of cancer of the blood cells, can cause a low white cell count. Certain medications and toxins can cause suppression of your white cells.
I encourage you to raise these concerns with a hematologist. After reviewing your blood work, they can help determine the next best steps in the workup.
