Last year I was regularly climbing around 4,500 - 5,300 stairs......just prior to, and after turning 73.
Towards the end of March I developed sciatica, which got worse and worse, (we were in Spain), and upon our return home and, since our doctor has relocated elsewhere, went down to Emergency where I sat for eight hours. X-rays were finally taken, and I was advised to take anti-inflammatory painkillers "And perhaps it'll go away".
Shortly thereafter I started sessions with a chiropractor who is now puzzled by my lack of response, since I appear to be in otherwise good shape.
He requested & received a summary of the X-rays which indicated that, on top of multilevel degenerative disc disease throughout the lumbar spine, I also have an unexplained 'osseous bump' which may, or may not, be impeding recovery.
Chiro suggested an MRI, and wrote a note to that effect to the Hospital because we still don't have a doctor, (apparently they're leaving in droves); I went back to Emergency to see if I could just hand in the request, (since they have all the X-rays & documentation), and have them schedule the MRI.....not a chance..so it's probably going to mean another eight hour shift.
(As an aside, I spoke to a hospital volunteer who was running interference for the triage......she mentioned that she didn't have a doctor either, since hers had relocated to the UK......figure, with all the medical contacts she must have, if she can't find a doctor....)
Anyway...the purpose of this post, (since you're likely wondering why I'm babbling), is to note that, however well you think you're doing today, tomorrow is another thing altogether.
