Welcome, PDM. I could write the same thing you wrote to describe my surgery some years ago: same age, same time of year for surgery, same basic surgery. Some say it takes a year to recover; others say two years. It was about this same time after surgery that I was in the hospital visiting a friend, and one of the nurses I had had (I called her Susie Sunshine because of her wonderful smile) said it was her 37th birthday. I realized then, as I was approaching my 47th birthday, that I felt only 37 years old. That could be a mark of recovery.
One year after surgery, almost to the day, I started a second job which I had to keep for 9 months; by the following summer (well over a year after surgery) I was on my way downhill. That could be a mark that recovery wasn't yet complete.
Now, over 5 years after surgery, I'm still here at VRcom every day, probably because the surgery changed my whole life. I suppose that is a mark that I still haven't fully recovered from surgery, and probably never will.
I wouldn't say that I am now 80-90% of what I was before surgery. In some respects I'll never be there again. In other respects, such as general physical health, I feel over 150% of what I was even several years before surgery.
