What Is The Prognosis For Elevated WBC And High Lymphocytes For 2 Years While Having Low Vitamin D?

My wbc has been elevated (14-20) for 2 years. I have been seeing a hematologist and she had done all the cancer tests. Even had a bone marrow tap. High Lymphocytes also. Symptoms - fatigue, sore muscles, over all just not feeling right. PCP has done RA, Lymes, Sed Rate - all normal. Vitamin D is low and i am on a supplement. I feel like no one is concerned anymore. I don t know where to go from here. Any suggestions?
