My GP has been the one to.listen to me. I have had CT of spine. Ultrasound of shoulder due to pain issues and the rhemstologist specialist ordered an mri and whole body bone scan to exclude why I had so much pain. Changing over my AI has made a huge difference and my bursitis (rapidly on my 1 month break) has finally resolved....so a lot of my pain...back, shoulders, neck was related to letrozole. (Ankles wrists and thumb also)The tests though stopped my worrying constantly about cancer in the bone. And my diagnosis of lactose intolerance has mostly stopped me worrying about abdominal /ovarian issues with the diet change. Survivorship is bloody hard at times.
