Sorry to hear that, @Zan - How long have you had the pains? If you haven't injured yourself, got a new bed or even new shoes (that could contribute to aches & pains) ... anything lasting longer than 2-3 weeks, really should be checked out.
How long since you've had a bone density test/bone scan/CT?
My mantra has always been: If in doubt, get checked out.
If it was me (and it happened last year) I'd contact my Onc and request they send a referral thru for those tests to be done, for peace of mind. (And it's good to have some new films as a basic 'history' too, for referral down the line.)
take care & all the best xx
