I had a little over 2 months of bed rest between hospital and home and felt the same way after birth. For months I couldn't even walk more that 4 blocks without feeling horrible lower back and leg pains. But I'm happy to report it does go away. It lasted for more or less an year but it does go away. If I could have done it differently, I would have probably gone to a chiropractor. I know several people that improved a lot with it.
