tenderness and pain

3 months ago I was on a high antibiotic. I noticed that the antibiotic was making my reflux symptoms more intense. I got a little upset over something can’t really remember what, but I had this tingling sensation go down my throat. It stopped where your esophagus meets your stomach. then my stomach got this warm heavy feeling. Which was really strange. I got really sick so I went to lay down. After laying on my left side for a while the heavy feeling eased up so I rolled over on my back. Just as I was about to fall asleep I jerked and raised my upper body up. When I did I felt a pop where I had the Warm sensation. It was tender when I touched it so I thought I pulled something, but when I rolled over, I felt heat coming up from my stomach. When I got up the next morning I could barely walk. The back of my mouth was blood red from the acid I guess. Did I give myself a hernia I’ve had countless tests done, and my doctors can’t find anything. The tenderness in my upper abdominal area won’t go away. I’m just trying to figure out what I done. If I pulled a muscle or what. I was completely fine before taking the antibiotic. It was 875mg twice a day. I’m also having tenderness along the bottom of my rib cage on both sides. But as I said my doctors aren’t finding anything. I’m at a loss. I’ve also noticed I’m burping a lot more than normal. I just want to know what I did or what I caused. I haven’t been the same since.
