Mets to spine, pelvis and thyroid--any advice?

Hi all! In Oct 2013 (at the age of 28) I was diagnosed with Stage IV breast cancer with mets to my femur and lymph nodes. I had a bilateral mastectomy, oopherectomy, and was treated with chemo and radiation. I was in remission since my completion of chemo in 2014. Earlier this week I was experiencing back pain and this morning the pain became so severe that I went to the ER. After CT and MRI scans were performed it was determined there are new mets to multiple vertebrae in my spine, my pelvis and a lesion on my left thyroid. Since it is the weekend, I have not had an appointment with my oncologist yet but I am planning on calling my onco office as soon as they open on monday.

Can someone with spine or thyroid mets share a little info on their experience? What should I expect in terms of disease progression/symptoms? I assume I will be treated with radiation but what other treatments are used for spine mets and thyroid mets?

Thanks!
