Low grade fever post breast augmentation. Should I be concerned?

I am experiencing low grade fever (99.7) today, at my p/o day 3. My chest area is very warm as well. I had my first follow up with my surgeon yest., and he did mention my chest was warm, however the nurse measured my temperature and it was fine. I do not have any redness, my breasts seem to be ok, visually. Today I was rather active at home and I was planning to return to work tomorrow. Are these normal p/o symptoms or should I be concerned? Thank you in advance for the time spent advising me.
