Has anyone been unable to go through having an MRI Scan done? I tried to have one done twice but on both occasions I had a panic attack and felt very claustrophobic. I am disappointed that it happened as I really need to have a scan done on my lower back, have sciatica and doc wants to see what is causing it, prolapsed disc or wear and tear. I am still in a lot of pain with it. I feel that I ought to try a third time, also staying still for 20 minutes worries me if I get uncomfortable as I also got cervical spondylosis and my back goes into spasm too. So I don't know what to do, should I try to attempt the MRI scan one more time? Any advice would be welcome!
