I Woke Up In The Middle Of The Night Saturday

I woke up in the middle of the night Saturday with pain around my solar plexus and severe nausea, it came on Suddenly so I thought I had food poisoning. I threw up a few times but now the nausea has subsided and I am eating solid foods. The pain is still in my solar plexus and comes in waves throughout the day. It’s worse when I lay down at night. Sometimes I feel like I need to belch but it’s difficult to do so.
