I had two PEs last year caused by an undiagnosed cancer. Both issues have been resolved, and I'm now about a year cancer free, and arguably in the best shape of my life at 45. Now that is not saying too much because I was In zero shape before and still have a ways to go, but still in overall pretty good shape now. According to the director of vascular medicine at the hospital I was treated at and continue to go to, I had the largest PEs he had ever seen on a living patient. That hit me because he is not a young man and this is a pretty high volume hospital/health system. I don't use an app because I'm just riding to improve me and stay one step ahead of cancer and things like PEs. I was never sick a day in my life before this so have no basis for comparison, but I've been told by multiple doctors my recovery has been "amazing", "remarkable", etc. I mention this not to put myself over but rather to encourage. I went from having cancer, being damn near dead, being told only 15 percent of people survive what I did, and they didn't understand how I didn't die to where I am at now. I just climbed a 7.6 percent grade that is about a third of a mile long on Friday so I think I have gotten on pretty well and hope you do too. Wish you the best as you move forward and happy to answer questions if I can.
