Went to gp on 2/2/2015,with severe headaches, which I had been treated and admitted to coventry university Hospital and discharged on the 31/1/15,saw gp,who felt that it was serious enough to admit me to new cross, was taken to amu, was eventually seen by nurse,after about a hour,and about another half hour by a doctor, then around half hour by a more senior doctor, was left in a chair for 6 hours in severe pain, no painkillers given, then seen by nurse again, then given painkillers, then put in a room with a chair and a hard examination couch for another 5 half hours, only given some toast around 4am even though they knew that I am insulin diabetic, most uncomfortable with blood sugar dropping... Not very happy, then after being admitted and tests exhausted and still not given an answer to what is and still is causing my severe headaches, doctor in front of me said to his colleagues "what's he still doing here" only offered an appointment with a neurology consultant, nothing else how or why it's on going.. Still feeling really rough and in pain. Not very happy, feel that i's a disgrace how I have been treated at the start and end. Staff are amazing but very understaffed.
