Januvia side effects

I have just been put on Januvia one per day. This is after being on Byetta and Metformin for 10 years. The Januvia seems to work fine, however I am concerned with the side effects that I have read about. Can anyone comment on the following.
Joint and Muscle pain
Feeling like I have a cold.
I don’t seem to have any other problems and had no effects with Byetta
Thank you
