Abdominal cramps, incomplete bowel movem

From a long time I feel uneasiness in my stomach ( sort of cramps) with no stomach ache. Initially I felt hurtburn too but that is gone now. Have contacted two general physicians. On 1st physicians advise I took pantosec d empty stomach for 5 days along with vizylac capsule. But it didn't go away. Then I contacted my family physician on whose advise I took Tablet Ranidom ( stopped taking it from today onwards, as I thought it wasn't helping much) for almost 10 days, 2 times a day after meals and oford lb initially for 8 days as I had throat bacterial infection. The issue is that I still feel I have stomach cramps and I feel my bowel movement is incomplete. This uneasiness is causing discomfort in day to day life. Any help would be appreciated.
