Dear Mizchelle,
Everybody has their own experience, and you needn't worry unduly if you're still not as energetic as you were before surgery. 90 days isn't really all that much time. While I was back at work half time in two weeks, and full time in four, I didn't really feel fully recovered for more than six months. New Year's, nearly eight months out, was when I recognized deeply that I was all the way back. Even so, I still get twinges from the fascia scarring when I'm working out, and it's been ten years. Keep up the self evaluation, and be thoughtful if something truly seems to be wrong or worsening instead of improving, even if that improvement is slow. Take care. Best wishes.
