Yes it can. I have the same problem I have had chronic hives for 6 months now and some of my symptoms are heartburn, its hard to swallow my food, and I feel my stomach is on fire then I break out in hives that cover my entire body. I was told that I have H-pylori and that is what is causing my hives as well. Check out this website www.drmirkin.com
