Sore joints after treatment?

Hi,

Has anyone experienced sore joints post chemo & radiation?  I finished treatment 2 weeks ago and have found that my feet and hands are super stiff in the mornings, sometimes overnight (although it has been cold here lately).  I spoke to my naturopath and he said this is very common.  I'm seeing my oncologist next week so i'll talk to him, but am just wondering if anyone else has experienced this?  I feel very old first thing in the morning!  (but i'm only 35!).
