The symptoms of this 20 y.o. otherwise healthy, thin (180#; 5'11") male are 2 weeks c/o nausea, intermittent, worse after eating, c/o bloating. No abdominal pain. Onset after beach week, crabs and grilled food; recent (this summer) history of wisdom tooth infection, strept throat, and ingrown toenail abscess. Recent (2 weeks) weight loss of 10 pounds. (2) doctor visits resulted in RX for phenergan, zofran, and most recently a 2 week course of Prilosec. Any ideas on next steps?
