So I was having pain in left side of abdomen mild intensity  since 2 months and recently increased pain intensity ,feeling nauseous and loss of appetite, I felt pain while defecation and bowel motion were mushy and liquid consistency so I went directly to radiologist and did USG ABDOMEN SELF Report said " Dilated Bowel in Lower Abdomen". I don't know what it means ,now what to do? Which doctor to meet ? Is it something serious??
