They do have open bore mri. I had one of those for a head mri and it was nice. Would have to ask if they offer one.
I was told it was likely a build up over the years of the discs problems. i know I had aches and pains come and go over the years.
:-(. I am told and read that it can heal but takes time. Hard to rest a back as we use it all the time. I have 3 children, young adults now, but I remember those days of run, lunge, lift and swing them on my hip and have the hip lean. And of course lifting wrong. My own fault I am now just learning to strengthen and engage core muscles.
My leg mostly left have that deep ache , tight like muscle, and like it is trying to go numb, heavy feeling.
I so understand how you feel so much.
I hope chat comes up soon, so we can talk more about it.
