Bloating, burping, mild discomfort ribs.

I have a history of chronic urticaria with symptoms like itching and burning sensations, though these have reduced recently. My current concerns include persistent bloating, mild discomfort or pain below my ribs on both sides (which I’m unsure is due to pain or bloating, as it only hurts when pressed), and lower back pain. The bloating is continuous, and I struggle to release gas through burping, which tends to be lengthy and requires effort. I also feel the urge to pass stool 3 to 4 times a day, particularly right after eating, but the stool is either minimal or doesn't pass at all. Additionally, I notice that gas is released only when I eat food or drink water. I drink alcohol moderately (twice a week or monthly) and smoke regularly, around 5-6 cigarettes a day. These issues are persistent and concerning, especially the bloating and digestive discomfort. The bloating part was happening earlier as well when I was having urticaria. if the allergy was severe, my burping was not happenin
