Getting "Backed up"

[KayCTheNewMe 50]

So this is a little bit of a longer story but it's a 2 part question. So the other night I ended up going to the ER 2 nights in a row for severe stomach pain. The first night I went was from 3 days of feeling like I had done crunches all day. The pain went all across my stomach and on the left side of my back. The doctors took 9 hours to not really find anything. They refilled my pain meds and set me an appointment to check to see if I had an ulcer if the pain persisted. The next night I had such a sharp pain that I actually fell to the floor and had the wind knocked out of me. Went to the ER again and within a short time they said that I was "backed up." They prescribed me Miralax which has helped quite a bit. Unfortunately my doctor stood me up today (waited over an hour in the room before just leaving) so I wasn't able to check for the ulcer but I am still having a very hard time drinking and eating because of the nausea. The pain is bearable so I don't want to push another doctors appointment until mine next week. So my questions are 1) What are some signs of ulcers and 2) What are some good foods to eat to not have this backed up problem again? My doctor told me to watch out for fibrous foods because of what it can do to your stomach/bowels so I'm not sure of some other options that may work. I am not at the point I can drink coffee again since I am only 5 weeks out so I cannot do that one at least for another month. THANKS!
