Is my acid reflux related to my food poisoning?

Five days ago I had food poisoning, from some chicken. Three days later I was fine, though still not completely recovered, as my stomach was still a tad uneasy. The next day I started to have mild heartburn sensation, but just took it to be just more uneasiness. I had chilly for lunch (I look now that that probably wasn't a good idea). By the time dinner came around it was starting to get worse, and I could feel the stomach acid start to come up a bit. I had a couple pieces of sushi, but no more than 6. Symptoms started to get worse from there, and it seems though the symptoms haven't stopped for about 12 hours. I got up this morning at 5 to find that I still had it, and that it was a slightly more painful than it was, as though my oesophagus is irritated or something. Could the acid reflux be related to the food poisoning? I'm also feeling quite gy.
