I felt a pain when I sat with tight belt in an unfavorable sofa. After I felt some gastro system upset, some real gas but also what I ate before could have contributed. The gas isn’t an issue now but still feel the pain in abdomen. If had an inguinal before feel kind of like that but in past it has been my staples from the repair. How will I know if I have the intestinal hernia that could get infected? When should I seek attention.
