Recently I've been having issues with my stomach. Like a month or two ago it felt super bloated and hard and I had lower right abdominal pain here and there. I don't have it anymore but last night I ate almost an entire bag of white cheddar popcorn and afterwards I had two soft bowel movements and my stomach felt a tiny bit bloated again along with the pain in my lower right abdomen again. Mind you, before I ate the popcorn I felt fine. What could this mean?
