I Got A Liver Punch A Year And A Half

I got a liver punch a year and a half ago. Nothing serious (no broken ribs, etc) and I was able to go back to work within a few days. Last week I experienced gastritis symptoms, starting on my upper right side of the abdomen. I went to the doctor who told me to avoid certain foods (like spicy food, which i eat a lot). Could this problem that I have a year and a half later be connected to the punch?
