My last bloidwork showed smudge cells. I know cll is a possibility. Is all also a possibility? What elae can cause smudge cells?

Not of diagnostic va. Not of clear value. If your CBC is otherwise normal then smudge cells can be ignored. By themselves alone they are do not imply a diagnosis of cll or all. Tell us the results of your CBC and differential counts so that we can be more accurate in informing you what it all means.
