I have been experiencing a flare up of my IBS which was causing diahorrea and crampy pains and generally getting me down. I went to my doc who was very understanding and has added spasmonal to my usual meds. It has really helped however after a few days of taking it I am noticing I have heartburn and am very bloated to the point where trousers which usually fit perfect have left a red mark all round my waist where they were cutting into me and I have horrible wind. It is like someone pumped me full of air! Its painful and uncomfortable. Anyone else experienced this from spasmonal? I am not sure if it is side effects or just another flare up.
