Will a knee mri make a difference if I'm having a good day or a bad day? Would anyone know? Will it matter if I'm doing ok at the moment compared to having a lot of pain in my knee? Trying to find out if this matters or doesn't. I know for an ultrasound on my wrist they asked me if it was a good day and I would like to know if it matters for a knee mri. Does anyone know or who I would speak to to find out? Thankyou.
