Hope you are feeling better. Your dinner sounded great, but I bet you wish you didn't eat it now! Makes me so mad when I get a partial blockage, esp when I figure out what could have caused it. Then I boycott that food item for the longest time!!!
Sounds like the combination of salad, eggroll (shredded cabbage/carrots), and then brocolli could have been the culprit. I really doubt if the green onions in the fried rice could have caused it. What were the very first things you ate? The salad and eggroll? On a fairly empty stomach probably?
Keep trying to move around -- drink fluids to stay hydrated, heating pad and massage your belly.
