42 here. I tore the tendon on my right bicep two years ago. I couldn't even hold a glass of water. Even at rest it was pretty painful. I went through physical therapy for about a year but, yeah, it's not the same. Every now and then I get little reminders, or "twinges", when I overwork it. But at least now I'm not in constant pain and I can pick my daughters up for hugs so it's all good.
. However, my occupation doesn't require anything too physical. Good luck to you.
