I took a 3 week trip to Europe before my hip replacement that had also been planned and paid for in advance. Others were depending on me to travel with them as well. I do not regret taking the trip--it was a once in a lifetime opportunity and I saw many places I may not be able to visit again. Like you, I felt I needed to take advantage of being there, but I did opt out of some of the most rigorous things. I also did some things that were definitely too much, but in the back of my mind I knew the hip was going to be replaced when I got back so I was mainly limited by my pain. My family members were supportive on one level, but on another, they could not truly comprehend the pain I was in. It must have been especially hard for you, wanting to experience VietNam, and also knowing you had to protect the hip. As Layla commented, it was so disappointing, and frustrating at times to be pushing through so much pain. My memories of the trip definitely include a lot of pain as well as all of the "travel wonder and joy". I had travel insurance but it was not as inclusive of a policy as needed had I cancelled the trip. Lesson learned. I will spend extra in the future to ensure I have a back door out in the event another body part decides to bail on me! Given how long you have been dealing with pain and limitations, I can only imagine how weary you must feel. Hopefully there is a sense of relief now that you are home, and you can structure things to give yourself a much needed break and recovery period.
