Im experiencing abdominal discomfort and feeling of fullness in lower abdomen to an extent where its uncomfortable to lie on my stomach

Abdominal discomfort: These symptoms may be due to pelvic congestion , ovarian pathology, pelvic inflammatory disease or an intestinal tract inflammatory process. Marked associated abdominal tenderness would favor the latter and would warrant an examination by a physician or surgeon as soon as possible. A gynecologist could evaluate you for pelvic problems. For severe discomfort go to the hospital emergency room.
