Hi, I had gone through your question and understand your concerns. These is suggesting degenerative changes of spine and it may be caused by disc hernia or by arthritis of vertebral body. In every case, it may cause specific symptoms such as pain in back, pain in legs and moving difficulties. Xrays is not so accurate so it would be good to do MRI scan. Also, treatemnt may be various and include medications, or more invasive procedures with needles and even surgery. It depends on how significant symptoms do you have. Needle sticks as you said are not risky but it may provide just temporary relief. Specific exercises or surgery may give better results. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
