I did not have back pain before starting Evenity, and my stayed in my upper to mid back. I do have 4 old compression fractures in my thoracic spine. It got worse the longer I was on Evenity. First it was just a few days and aleve or tylenol would help. By the 8th shot I was taking meloxicam every morning and tylenol all day. Then I started taking tramadol as needed. I made it through 11 shots before calling it quits. I still have some back pain but not like it was. I'm off the meloxicam because it eventually caused GI issues which I am still dealing with a month later. I still take tylenol and tramadol as needed. I have also had steroid injections in the most painful muscle knots in my back and I am getting a new MRI in a week to see the status of my spine. I'm now taking Forteo. I hope you can find relief for your pain.
