I HAVE BEEN HAVING EXTREME PAIN JUST UNDER MY STERNUM, RADIATING TO MY BACK, WEAKNESS TREMBLING AND SLIGHT NAUSEA. IT LASTS FROM SEVERAL MINUTES TO AN HOUR OR SO. IN MY RESEARCH I HAVE FOUND SYMPTOMS THAT INDICATE IT COULD BE PANCREATITIS, COLITIS, ADRENAL FATIGUE, CELIAC DISEASE AND A NUMBER OF OTHER THINGS. THE PROBLEM WITH THAT IS INSTEAD OF LOSING WEIGHT, I'VE BEEN GAINING...20#s IN 2013 AND IT'S 99% IN MY ABDOMEN. I HAVE ALSO HAVE SEVERAL TIMES A DAY, LOOSE (OR JUST PLAIN WATER) VERY FOUL STOOLS. ALSO LOTS OF GAS. I'VE HAD THIS PROBLEM FOR YEARS BUT IT WOULD ONLY OCCUR ONCE MAYBE EVERY 3-4 MONTHS. LAST YEAR THE EPISODES OF INTENSE PAIN HAVE GOTTEN INCREASINGLY CLOSER. IN FACT ONE NIGHT I HAD 4 EPISODES.
