Unfortunately, that shoulder pain can last a long time. For most people it's the most painful part of the recovey. Walk, walk, walk. Walking was what worked best, and I think others have discovered that to be helpful as well.
Call your doctor's office and get their advice regarding getting your bowels moving. Joy (couchtater) said her doctor recommended mineral oil and says it was gentle and effective.
Unfortunately at this point in your recovery pain is to be expected. Be sure to call your doctor about the bowel issue. You are right about the codene.
Hang in there!
