My 62 Year Old Husband Has Sparatic Pain Measuring 6

my 62 year old husband has sparatic pain measuring 6 to 8 under his right rib cage after eating, 4 months ago he began to lose weight and appetite. Dr. did colonoscopy finding 3 small areas that were tested and found to be of no concern.. He was taking dicyclimine 3 xs a day, thats been changed in the last 4 weeks to a new stomach med 2 xs a day. He takes amolodapine 10ml one time a day and levoxal for thyroid issues which has worked well to now. THIS pain has been ongoing for at least a year. the weight loss is my concern but the Dr. doesn't seem bothered by it.
