Rather take pain killers than getting a life changing procedure

A bit dissapointed. I went on refferal to neurology in kimberley it is 300 kms from us. Then they did xrays and an MRI scan where they picked up why i have so much pain the past few weeks. They want to do a pain block and now you decline authorization for this procedure. So i can rather drink pain killers every single day and feel like a zombie because it is schedule 6 pain medication than to go for this one procexure that will propably change my life and take away this pain
