I read in the paper the other day about double jointedness. I'm double jointed it was saying that if you have IBS then this can make your joints more susectible to breaks and sprains. I have noticed my son is slightly accident prone. He's broken at least 2 toes in the past. He's got a fracture on one of his fingers 1st joint of the ring finger. He also seems to have bruises on his legs from walking into chairs. He laughs about it. There is a name for the double jointed but with the IBS it becomes a syndrome. You just want to wrap them up in cotton wool.
