Hi all! Extreme neutropenia (100) was found in 2014 because I (40 year old female) had an emergency appendectomy. My Hematologist did all the testing, bone biopsy, CBC, & genetic. It's not genetic and no answers. I had a lot of sinus infections that I couldn't shake. I then started giving myself neupogen injections every certain number of days in 2017. The doc keeps my neutrophils at a low normal. She says they don't know if I don't produce enough or if I do and my body destroys them. Anybody have similar condition or any thoughts?
