Hi Michal,
Unfortunately your doctor and physiotherapist are misinformed. Epi-no is definately recommended for a second birth if an episiotomy was done, or if there were tears that required stitching. This is because there is scar tissue which is less flexable and doesn't stretch like regular tissue. It is well worth every cent to try to avoid needing stitches this time. Especially in your case where the stitching was perhaps not done so well and the healing was difficult. All research shows that the epi-no does not leave you "stretched out or widened" and in a few months you are back to normal. There is no connection between the epidural and using the epi-no.
