My husband has extreme pain in his lower abdomen just above his public hair, as well as in his back. He has a fever of 100.2 and has had it for almost 24 hours. He feels like the pain is from being constipated, but that isn t causing the fever. I am wondering if it could be a gull bladder attack, he has large gull stones and debris in his gull bladder but he has never had an attack. Trying to decide if we should take him to the ER.
