I have been having abdominal pain on both horizontal sides of my naval. The pain is not severe but it comes and goes. My head also feels heavy most of the time and when I rinse my throat with water and salt I run out of air and fight for air and fee that l will almost die. Also I have been having some throat pain. Its not bad and I notice it only when I swallow spit. I did over 10 test but with no results. I am worried and I want to know what going on with my body and if stress might be a cause
