“We were in Machu Picchu about five years ago (amazing) before I was diagnosed with scleroderma. I often wondered if that was why I struggled with the altitude, as I now have PAH. We also went to Antarctica two years ago on a cruise. We did not get off the ship and it was also amazing. I had no problem there. We might be at the end of our travels but they were all so wonderful experiences. So keep on traveling if possible. Love your blogs.”
