I have been told that because of steroids my back and bones are in a bad state. Constant back ache in my lower back walking standing is so so painful. I'm on morphine patches for pain. My question is I have to have MRI scan done for my lower back and I'm very clostaphobic. Is your head out of the scanner? I've been told I can get a sedation from my doc. Please help. Hope you are all ok take care.
