Nervous and scared

Tomorrow i go in for my bone scan to rule out what causing my bone pain weather its caused from the disease i have neurofibromatosis or my cancer spreading that one thing there very concerned about or it can be caused from the cancer medication im on Arimidex and could be having the starting of ostieoprosis and if that the case they will change me to a different mediaction and then i will have to be on injections for it and managed with pain medications.
so tomorrow i have my scan done and then i go in friday afternoon to go over the results with my cancer doctor so i will be posting an update friday night with the results.
