Hi, just trying to do some reserch..I have had an elevated wbc since about 2006. It has been in the high 10,000 ,11,000 mostly. I am fatigued more than usual and last year got pneumonia? and the year before that a lung infection. My joints are sometimes stiff...mostly my knees and neck..lately my wrists and hands...last week I was limping because I felt pain when I stepped on my left leg. I am going on 50. I walk and stay active and eat right and take vitamins . Also, I was recently diagnosed with microscopic cholitis (an autoimmune disorder). I don t feel like myself and feel there is an underlying issue causing my body to react this way. I saw my doctor yesterday and he is referring me to a hematologist .
