I'd a small umbilical hernia in my 1st pregnancy 15 yrs ago, it was repaired by itself, then again in the 2nd pregnancy, is truss useful to me?

Well.: If you the hernia does not cause any symptoms and you are ready to comply with the regimen of a truss go ahead. However, in time your abdominal muscles may get weaker and the hernia may grow in size and than you probably have to repair it anyhow. Have a surgeon see you and let him guide you as what would be the best for you. I would wear the truss only as a temporary measure.
