I had surgery yesterday and everything went well, I went home the same day. I had some water, sugar free popsicle and little bit of a protein shake yesterday. Today just water so far, I am scared to drink too much how will I know when to stop drinking? Also I have pain in my shoulders and neck very uncomfortable, anyone else experience this? Last question is about my chest, it hurts like someone is pushing down on it, lots of pressure, normal??
