I've had pain(throbbing pain) around my entire abdomen and becomes intense if i'm walking or pressing my stomach. lost appetite, my eyes also has needle pain, and feeling a bit tired with lots of heaviness on my left hip. this isn't the first time.

Doctor can evaluate: Many things are in the abdomen: stomach, pancreas, liver, small intestine, gall bladder, appendix, large intestine, abdominal muscles, kidneys, etc... An exam by a primary care doctor can help figure things out. Pain in the right upper abdomen can be due to gallstones, pancreatitis, stomach ulcers, etc... Stomach flu, food poisoning, other infections, etc., can also cause pain.
