Have always had 'lower back pain' for 60 years.In late 70's got a new chiropractor, 1st thing he did was xrays and a minor tweak. went back 2 days later,sitting in exam room waiting for him, looked at charts and xray on the lighttable,compared and saw damage to lower back, doc comes in and I said 'gee, that guy has to be in pain, those don't look good'. he said 'you tell me it YOUR xray ! L3-L4-L5 have maybe 5-10% 'discs' left. He'd tweak me every 2-3 months, depending on whatever 'silly' thing I'd do.
About a year before the Chinese Virus came, I got into the habit of a simple, easy exercise I do when I go to bed and have NOT been back since.
I lay face down,arms crossed, head on arms( gotta breath...) ,I then curve my back up and tighen the lower back muscles,hod for 15-30 seconds, relax. Do this 4-5 times. Once you figure out how to do it ,it's easy and pain free.
I think it helps 'build up/tone' the muscles around the spine. All I KNOW is that for 6 years I haven't forked out $40 per visit,2-3 times a month ,I'm NOT in pain and can do 90% of what I could 10 years ago.
May not work for all, but maybe worth a try.
