Thanks, all. Pain has lessened today and I have managed to keep a few spoonfuls of natural yoghurt down.
Hester, if the call out doctor is right, and you are over 40 you may well have it. I think that it's ok so long as it doesn't get infected.
Tiz, I only eat gluten free bread, and that rarely and I have a very high fibre diet.
Annie, I used to take Fibogel but it stopped working after a while so I am on something similar but maybe a bit stronger.
OH has just bought me some pro-biotic drinks. He asked for a big pot of live yoghurt and whoever was helping him shop in Tesco (one of their staff) said they only sell the small bottle. Not true. I often buy the big pots. At least I've got something. I'm due to go out for my Samaritan training tonight and I so hope I can make it. If I miss any of the sessions, I will have to wait a few months until they are training again so I can catch up. I don't want to wait so hopefully will be able to go.
