Any one agree that doctors are useless?

I have had sciatica for 9 years now and last year the pain became more severe with agonizing hip pain, numbness and pain in my thigh, groin pain and back pain. Doctor referred me for physio but therapist said as physio did not work 1st time was unlikely to work again. One doctor told me to get a hobby, other doctors said the groin pain may or may not be related to the back pain, no doctor will let me have an x-ray or mri scan and today the cherry on the cake. I saw another doctor and was told to get plenty of fresh air, walk a lot which i already do and which the physio said did not count as exercise and wear a belt when i wear trousers. I have given up now and resigned myself to chronic pain. The only way i can sleep is with copious amounts of alcohol, painkillers and sleeping pills. I had hysterectomy 10 years ago and my back was never the same after.
