From the last 3-4 days i am consipated, not able to clear the bowel fully. From yesterday i am having heaviness in right upper abdomen which leads to some kind of heavy burpings continously. Due to this pressure in right upper abdomen, i am having a headache at the right side of the side. It flactuates when burping occurs. Feeling of something stuck at the right side throat also there.Before 2 months i had taken naturolax A for consipation. As now i have red shiny rashes and patches on my arms also. Can i take isabgol powder for this stomach issue?. Whether only taking isabgol powder causes any type of allergy to the body?.
