hello,I am 81 yrs old and never have had medical issues. when I tripped & stumbled I had to go to er room due to the pain. I was referred for mri which showed spinal stenosis, narrowing of the spine. from my 8 months of therapy, pain meds, & doctor appts. I have been diagnosed with radititiicus, lumbosacral/ static nerve pain. question is my spinal stenosis partly to blame for sciatic issue or can I attribute most of pain to trip? even though severe stenosis was noted in the mri I didn t have pain & medical problems until the trip/stumble occurred.
