Its now been over a year since my husband has been passing blood,and had chronic nausea and pain.Hes lost nearly 5 stone,Hes had 2 colonoscopys, 2 ct scans and 1 endoscopy, hes having another one next week. And still they havn't found (or seen) anything. I would just like to know if anyone else has been through test like this and they,ve missed things? Please im just watching him waste away,and the hospital arent doing…
