Sunday after I strained my back, I could not stand up or sit down without
pain in the lower back. I was basically useless, walking was a real
strain.

When I used to do that, the doc had said simply take a scrip (now sold OTC
as Aleve) and lay about for 2 weeks..No chiro.
I took a week off work but the healing process wasn't coming along well. A
co-worker finally talked me into seeing his Chiro..
The chiro did his thing-said that although the pain was in the lower back,
the vertebra out of place was up higher, just neath the shoulderbaldes.

WHAM !! He did that twice and said to come back for another treatment in
2 days. I got up the next day and the pain was 95% gone.
Day after that, it was fine..no pain-No 2nd visit.

I reinjured the same spot about every 5 years or so. Chiro fixed it every
time..Lucky for me.
