Puny Immune System Years after Chemo?

Outfield

Once again, I am running a fever and feeling kind of crappy. This happens so often. I don't get as severely sick as I did during the first year after chemo, which I finished nearly 5 years ago, but it still feels like it's way too often. My doctors have no suggestions. Does anybody else experience this?
