  In this paper we calculate modifications to the Schwarzschild solution by
using a semiclassical analysis of loop quantum black hole. We obtain a metric
inside the event horizon that coincides with the Schwarzschild solution near
the horizon but that is substantially different at the Planck scale. In
particular we obtain a bounce of the two-sphere for a minimum value of the
radius and that it is possible to have another event horizon close to the r=0
point.
