Abdominal discomfort

I am a 29 year old male. From the last 3 months I am suffering from abdominal discomfort characterised by abdominal burning, fullness, bloating, excessive flatulence and pain in the lower abdomen (pain is dull in nature and it feels as if some electric current is radiating from the navel to rectum). Pain is not relieved on passing flatulance. These symtoms are present throughout the day and aggravate on exertion, emotional stress and after meals. The stools are normal on most days with occassional semiformed stools (once or twice in a week). I feel lethargic, depressed & am always conscious of my abdomen. Many a times it feels as if there is something lodged in the rectum & as if stool will come out. I got LFT done in July 2005, serum bilirubin was 1.8 mg/dl (normal 1 mg/dl) and SGPT was 78 IU (normal 40 mg/dl). Other parameters were normal. Whole abdomen ultrasound showed gaseous abdomen with mild fatty liver. I have stopped eating fried food. I have normal thirst but don't feel like eating anyhting as it aggravates the symtpoms. I experience burning of palms & sole of feet. There is excessive sweating from feet with highly offensive smell. I am intolerant to heat. I started rabeprazole 20 mg bd half an hour before morning & evening meals. Abdominal burning improved but bloating, fullness, pain & flatulence persisted. I also tried aloes 30 4 drops 3 times a day, bloating improved. I am taking arsenicum album 200 4 drops 3 times a day for last 2 weeks. Symptoms have improved but not resolved completely. Pain in the lower abdomen persists. Please help.
