Hi, I just wondered... stupid question but there's always mention of spasm with IBS and I wondered what exactly does that mean? How does it feel? I've got a feeling like I've got a twitch in my bowel low left side - is that a spasm??? I suffer constipation and wind. This is staying in the same place and feels odd - I've not really felt this before but I do get pain, bloating and 'grumbles', this is different. Any info. appreciated, thanks!
