I'm having continuous, dull achy pain in the midline upper abdomen that sometimes intensifies and radiate to my back. I'm 10 days post-partum and pain has been present x 3days. Normal, unmedicated vaginal delivery. Hx of near-total splenectomy (with post op splenic vien and portal vein thrombosis 2+ years ago, was tx with anti-coagulants for 6 months and had clear CT scan), mild-moderate h. sperocytosis. I had constant heartburn during the pregnancy, which subsided after the birth. Any dx ideas?
