I am so sorry about your suffering. I had also a very bad experience, but more than 22 years ago: it started with a hip replacement and then all went wrong. I ended up with a total of 5 surgeries in 2 years of which 4 were replacements. I had also an infection, broken bones, and last but not least a pulmonary embolism. At that time I was 60 years old. The last 2 surgeries were done by another surgeon and at least he made it possible for me to walk with one crutch without pain for the last 20 years. It is still working! Of course, due to all the surgeries AND my advanced age, I can not walk long distances. But no pain. I hope you will be all right!
