To Sassy and all who were so kind to answer my query:
thank you very much. your experiences sound similar to mine (pain after finishing chemo and starting herceptin, etc.).
and yes, sassy, i, too, have been "slammed" into menopause by chemo. So that may be a contributing factor as well.
My pain is manageable but very annoying because heretofore, i've never had any constant pain in my life (pretty wonderful/spoiled, i know.

)
I'm going to resume the exercise I do at a local "Curves for Women" and see if it helps me - I may also try an Alleve or two every now and then.
Thank you all so much for taking the time to give me feedback. This cancer stuff can be so frightening and all-consuming....
best,
jane
