Chills were an intermittent symptom for me, and I periodically get those even today. As always, keep the doctors in the loop on these. Taste is very individual -- at this point it is more likely a reaction to chemo rather than radiation. My mother-in-law has been treated for lymphoma for the last 2 years, and has had only chemo. Her taste has been almost as disrupted as mine.

Nothing to worry about, in all likelihood, but I would mention next visit with the doctor. If you feel the need, call ahead and mention it now.
