Hello good morning Doctors! My husband had a severe headache for 4 days now and i took him to the ER yesterday because of high fever also plus the headaches and they gave him 4 differents kinds of pain medication such as morphine , toral? And none of the medicines cured his headache he s blood pressure is low to normal but he is in an excruciating pain again and they don t want to do any CT scan because of bp is low.
