hip and back issues

Hi.i went to see a physio earlier expecting exercises for my back and hip problem but it was a chat with a physio and i mentioned i had a doctors appointment on friday to talk about my hip xray and he said i can tell you the results now,okay i said not expecting to be told beginning of arthritis in my left hip and servere in my right.I am 65 at christmas.The pain has been off the scale for months i just thought i had a trapped nerve so i am in shock.He told me i can go on the list for a new hip or try an exercise club,which i will do first.I really feel sick with shock.He tell me the pills i am on are for nerve damage to so good just over the counter drugs or naproxen,which i have had before but does not suit me,he said the physio will not help with pain and if pain we my main focus best to go on the list for a hip.Please help me i am so lost,also back of my mind lost my dad after an operation he never woke up from what was told was a daily operation and they had not lost anyone in seven years so tonight it is all going through my head how can this happen to me and what should i do.many thanks.
