Since the parts we are discussing do not have as much blood flow they take a loooooong time to fully heal, and are not as strong as they were before. It is worse if they tear again, which mine have and were repaired again. One side tore again and I was told between tears and repairs there is not a lot they can do for it with any success.
I sold my higher powered bow but wish I had kept my Matthew's Genesis (25 lb?) that I used for recovery the last time. I actually got a few carp with it when I put one of my bowfishing reels on it.
There are a number of things I used to do that I have relegated to the "I used to do that" file. Plus I am more careful with what I do as the one side is a bit limited on what I can do with it these days and is easily hurt worse.
Until they come up with some kind of DNA reading repair solution that will restore things to how they were 'supposed to be' I am hosed it appears.
Some times there just ain't no fixing things. Worse at my age I am afraid.
