Diagnosed recently cll stage 0 but just started having abdominal pain left side, feeling bloated. wbc 13, 000. will i need chemo if nodes in abdomen?

Here's an idea: Today, it's customary to subtype cll by its genetic markers. It's actually about a dozen different diseases, some aggressive, some not. I'll bet that your hematologist has already done this, and your tumor mutation / translocation profile will be more helpful as a guide to treatment. Whether your spleen is big or not is much less of a factor than other parameters.
