Hello! Simply get a Xray abdomen to see for any partial intestinal obbstruction. If it is not there then there is nothing to worry. For constipation take stimulant laxative like bisocodyl or picosulphate instead of psyllium husk rather take low fibre diet. It can be simply IBS but you havent mentioned about the duration of the symptoms. You shuld also take antispasmodic agent for mild discomfort like mebeverine thrice a day, a proton pump inhibitor for discomfort after meals. Few important things about IBS. 1.It will never harm you 2. it has relapsing remitting course 3. Try to avoid food which aggravated your discomfort 4.Life events, stress, and anxiety may exacerbate your symptoms I hope this will helpyou.
