Hi there! In answer to your question, the not being able to breathe part really scared me too. The day I came home from surgery, I felt like I couldn't draw in full breaths, like there was a sharp pain in my chest. I quickly called my surgeon and they informed me that certain people have to deal with the "sharp breath" feeling because of the rib retractor they have to use to hold you open during surgery. I started to panic, but kept reminding myself that the feeling was normal, and just as my surgeon said, it got better within a week. I no longer feel it at all, and I'm 2 months post-op. I've lost 67lbs and feel great. I hope you have great success too! We'll be praying for you! Blessings!
