Hi I Have A Issue With My Fiance He Has

Hi I have a issue with my fiance he has stomach ulcers recently has been taking omeprazole to treat it. He has now ran out he went to the doctors as once finishing his course he was suffering again and went back to his gp. They have told him that he has to go for test at the hospital for a endoscopic which is not till 27th of october. For the last few days he has not slept much at all he is doubled up in agony and drinking alot of milk to try and soothe the pain but with not much luck and doctor wont perscribe them till he been for test's. To me this is not on and he is in alot of pain without his tablets and cannot cope untill 27th october. yours sincerley miss natalie Lawrence
