Hi I have left side abdom pain. It feels like its being sucked in every few sec.-gnawing. Pain?

Left sided abd. pain. Causes of recurrent abdominal discomfort as described may be identified by first addressing signs/symptoms so as to localize the organ involved: vaginal discharge or bleeding, alteration in periods, pregnancy risk? Fever, nausea, vomiting, altered stool pattern, blood with stool, tenderness, distension? Painful urination, blood in urine? Recent trauma, herniations? Age? Gender? Other risk factors?
Suck in? Dear spongebob-- have to be more specific about the pain. Is it lower or upper left sided abdominal pain? Are there an other symptoms such as nausea, vomiting, fever? Have you had previous surgery?
