My husband felt unwell, his stomach started hurting... a heavy feeling under his ribs, which turned out to be hepatosis and lipomatosis of the pancreas. He's treating himself for now, we only went for an ultrasound. Work won't let him rest. Has anyone dealt with this nasty condition? How long did the treatment take? My husband is on medication and a diet.
