What would cause pain in to of stomach to my belly? its really swollen and over the last two week ihave had2 blood transfusion.don't know.

Swelling may be bad: Retained air in the gut can certainly lead to bloating. However, a "hard" abdomen raises greater concern, such as fluid (ascites) in your abdomen or intestinal blockage. Ascites can be due to significant liver disease, infection, perforation of the gut, trauma to an organ with bleeding, or even cancer. Intestinal blockage, if present, risks rupture, peritonitis, death. Please get evaluated now.
