Surgery Post Op Hospital Experience.

So they took me back to the operating room and I don't remember anything but waking up in my room. I woke up and felt really good for someone who just went through a major surgery. All my family was there and asked me how I was feeling. Then I was out. Nurses came in and out all night due to my hemoglobin levels were very low and they said that I might have to have a blood transfusion. Also my blood pressure was extremely low. They also put me on potassium which hurts like the dickens. Makes you feel like your whole arm is going to fall off. 
I woke up in and out for almost 24 hours. When I did finally wake up good the pain started. So I had my cocktail (dilaudid pain killer)in my iv and I was pretty happy. The pain was mild and I thought this was going smooth.
3 days after surgery my right side  starts to hurt severely and I don't know what is going on. I have this rash and I kept telling to nurses that it hurt. So they called the Dr in. He said it was because I was laying in the bed. By this time I was getting up more and going to restroom quite frequently and I can look in the mirror. The red rash took over most of my right side. and the pain was still there. I was crying by this point (day 4). I asked the nurse on duty to please call the Dr back because the pain meds did work and it hurt. She looked at my side and saw the rash. My Dr had to go out of town so they called the Dr on call. He was very nice. Ordered some blood work and looked at the rash. He never said what it was but it put me on more potassium and loads of antbodics.
They kept monitoring everything, telling me to get up and move recording bowl movements and then on day 5 I think the nurses from hell came to visit me. They were not bring me my pain meds like they were suppose to and would have the cna come and turn my call light off not even ask what I needed. Once left me setting there almost an hour. I understand they have other patients but I am still a patient. I was not very needy, I might have pushed the call button twice in a shift. Thank the lord they were on there 2 days and the nice nurses were back. I seemed to have a different nurse everyday/ night. That can be a nightmare because they don't read your chart and you have to tell them the problems from the start to finish every time a new one came. I know they don't have a lot of time but they can at least read why you are there.
I didn't get to leave until day 8. It was nice to finally go home. I had a drain port in my left side of my stomach which would have to be removed a few day later. I was miserable and didn't want to get out of bed. I was having bowl movement at least 4-6 times daily.
