By My kid sister was released from hospital today. They've diagnosed IBS with a swollen bowel. She never said if they'd prescribed any medication or if she has any follow up appointments to attend. She's still in a bit of pain but seems to be a lot better than she was on Friday night.
Talishia used to suffer from IBS, and she took a peppermint tablet that I can't recall the name of. I will find out for you. Also there is a tea called "Digestif" that helps with IBS as well. Again, it is a peppermint flavour drink. Might be worth a go for her if she wants to.
