I also have IBS-C that was in remission until my covid came back a year later. I only eat around 5. When I put any food in me, the rumbling begins and with constipation, comes the pressure. I end up using a Fleet glycerin suppository. IBGuard helps calm the symptoms and it’s over the counter. I have lost 10 pounds and most doctors want to discuss my weight. I too, am not happy with the prescriptions recommended. Amitriptyline helps with nerve pain.
