Here is a little info about monocytosis. Obviously it is being caused by either the hep c or the treatment is bringing it out. If your doctor said it is not a problem and he checked it out, you should stop worrying. I you still worry, go and get a second opinion and be sure to ask the doctor for a full explanation of what it is.
Good luck, Marcia
Monocytosis is an increase in the number of circulating monocytes. In humans, 950/μL is regarded as at the upper limit of normal; monocyte counts above this level are regarded as monocytosis.
Causes
Monocytosis often occurs during chronic inflammation. Diseases that produce this state:
Infections: tuberculosis, brucellosis, listeriosis, subacute bacterial endocarditis, syphilis, infectious mononucleosis and other viral infections and many protozoal and rickettsial infections
Had swollen lymph nodes through out treatment and actually had a lymph node biopsy with out much to report, seems to come with territry, although there does seem to be a link with non- hodgkins lymphoma
