Someone mentioned a cat scan and MRI if you have pain, I had agonizing pain for more than a year, the doctors couldnt find anything. Finally I sought out a highly recommended doctor (not an oncologist) who ordered a myelogram which showed mets on the nerves of my spine. They were barely visible and the MRI and CAT scan had showed nothing. Prior to that myelogram, the doctors treated me like a crazy woman and I began to wonder the same thing. Like I was making up the pain!
So I say consider strongly that it is healing but also make sure your doctor has done his or her job.
Best wishes,
