The pain does suck at first but it will get better, you are just two days out, you have to realize that you are going to be super weak and can't do a lot. For the first week, just taking a shower exhausted me. My advice- rest, you can get up and walk around but you aren't going to be able to walk a mile each time. As long as your getting up throughout the day you will be fine. Don't try and take on the world two days post op!!! Also go slow with foods if your able to get jello that's good. For the first week all I could get down was Popsicles! I would stay away from the oatmeal for awhile. Good luck, take some deep breaths and don't stress!
