hi my dad has a fever lower left quadrant pain he is tired and no appetite?
your dad may be having some intra abdominal pathology causing the pain. needs a abdominal scan to come to a diagnosis. feeling tired nausea weight loss can be due to abdominal koch’s. get his blood checked for igg igm and elisa for kochs. a ct scan of abdomen with contrast will be helpful to rule out other pathologies
