### input:
I recently started riding a bike. I havent been on one in years. The day before yesterday was the first time. Afterward I felt as though I had been punched in the stomach. My actual stomach just below my ribs. My lower abs felt fine. I found it difficult to breathe as a result.I thought maybe it was the workout and I was just sore but the pain felt internal.The pain subsided. I rode again today somewhere and shortly after (maybe 45min) the pain returned until I ate something. After riding back today, I had no issues. Then suffering from a mild heartburn hours later (which I often get) I took some alkaseltzer. Then I had yogurt with granola and some chips with mild salsa. I didnt over eat. The pain returned worse than ever about 30min later. My bowel movements have been regular.My stomach is inflamed and I am bloated with difficulty breathing. I am worried it may be a hernia. But Im wondering if a dietary change could be to blame?

### output:

Hello! Thank you for the query. This sounds more like a peptic ulcer. The pain usually appears after a meal. Nausea can be present and chest burning. If it is about hernia, it can be hiatus hernia (a kind of internal hernia where a part of stomach gets to the chest cavity). I suggest you to visit your doctor, have blood work and abdominal ultrasound. Gastrostomy should be next. During this test also Helicobacter Pylori infection will be verified. In case of its presence, antibiotics are necessary. In a meanwhile please avoid fatty foods, spicy foods, coffee, alcohol. Hope this will help. Regards.
