Bone Mets or Not?

So I was diagnosed with breast cancer Christmas Eve of 2014. I had a DMX on February 15 of 2015. I had reconstruction and implants put in May 4th of 2015. July of 2016 I fell out of my RV and landed on my knee on concrete. It was quite painful. 2 weeks later I woke up one morning and my right hip was all hiked up on one side and I could hardly walk. I went to the chiropractor and my hip had shifted in 2 different directions. Had an adjustment and continued to see the chiropractor. I started having a lot of pain in my lower back, hips, legs, and eventually up my back and into my neck. I have fibromyalgia and according to the X-rays the chiropractor took, I also have degenerative disc disease in L5 along with degenerative arthritis in the same area. I was not getting any better and decided to go to an orthopedic Dr. For whatever reason, it never occurred to me to talk to my oncologist about this although I did tell her what had happened and what I was doing about it. The subject of mets never came up. I got the MRI and saw the orthopedic Dr. a month later. He showed me a spot on L5 and said it was suspicious for Metastatic disease. I had him send the results to my oncologist. The orthopedic Dr. also ordered 3 more MRIs with and without contrast. Took almost 3 hours for those and I could hardly walk afterwards. I had them send those results to my oncologist as well and I actually saw her before seeing the orthopedic Dr. again. She said they found 2 spots. 1 at L5 and 1 at L2. She said it was highly unlikely that it was mets but because the orthopedic Dr had put that in the results that she would have to do a Nuc PET/CT scan to rule it out. She also said that it was more likely cyst or blood vessel malformation. She also stated that she did not know what cancer looked like on the scan and is dependent upon her radiologist to tell her anything. She said if if showed up on the PET scan I would have to have a bone biopsy. I saw my Orthopedic Dr. 2 days later and he showed me the spot on L2 and the the spot on L5. One is dark and the other is kind of a light color. I told him what the oncologist said and his response was that it was not cyst. He said they see those all the time and that's not what I had. He also said it was not blood vessel malformations because those are rare and for me to have 2 of them would not really happen. He is convinced it is mets. So I had the Pet scan on Wednesday. I called my oncologist and spoke with her nurse. I asked that either the Dr. or the Nurse Practitioner call me back and let me know if was going to have to have a bone biopsy. The nurse called me back later that day and said the Dr. said everything looks pretty good and I don't have to have a bone biopsy but I absolutely cannot miss my appt. on Monday. She repeated this twice even though I was not asking to skip my appointment. The talk with the nurse happened yesterday. I did figure out today that I missed my monthly appt for a Lupron shot this past Monday. So I guess she could just be saying that because I did miss the shot. But she can't give me the shot on Monday because I can't see the Dr and have the shot on the same day since my insurance won't pay for the shot if I see the Dr on the same day and it cost 1700.00. So I have the MRI scans and can see the spots. I also have the report from the radiologist that read it for my orthopedic Dr. I do not have the report from the radiologist for my oncologist and won't see her till Monday. I am confused because 2 different doctors are saying different things and I am also confused because I see the spots. Could it be anything other than mets? Also I had a bone scan in march because my liver enzymes were elevated. Nothing showed up on the bone scan.
