I'm 3 1/2 months out of surgery to repair thoriac aortic aneurysm. My sternum/scar area, is relatively pain free, unless I strain or touch. Understandable. I'm still having to take pain meds to control the pain in my upper back. with intentsity of pain coming and going. I'd like to ask the folks in this forum if they have experienced such pain and how long it lasted in their case.
