For short term use there is no prob for its use. It will reduce pain and slightly improve bone strength

Hi, Calcitonin is a naturally occurring hormone. It helps regulate calcium levels in your body and is involved in the process of bone building. When taken by shot or nasal spray, it slows the rate of bone thinning. It also relieves pain that occurs when the bones in the spine (vertebrae) break and collapse on top of each other (spinal compression fracture)... Usually the benefits of the medicine are more important than any minor side effects...
