Has anyone here been through this?
Extensively.
There may be congenital reasons too, but once upon a time, I had a bad day of snowboarding that left both ends of my spine compressed. Being in my 30's at the time, there was no stenosis yet, but the disks were at about 20% of normal height. Pinched a nerve in the cervical spine, right arm went numb. After six months with no improvement, I saw a chiropractor. A year an a half of treatments 3 days a week, and sensation returned. X-rays showed disks at about 80% or normal height by then.
25 years later, time and gravity did its thing, disk height collapsed and spinal canal narrowed. My left arm went numb. By this time, abnormal bone growth was the issue and no amount of cracking my neck, having something pull on it or rubbing Bengay on it were going to make any difference. After several consultations and different surgical options, I chose a surgery that was pretty invasive, had a long recovery time, but left my spine strong and me able to do everything I was doing before.
Time caught up with my lower back more recently too and I've had two surgeries within 14 months to relieve pressure on nerves there too. The second one was a revision, as the first caused issues that weren't present previously.
The one piece of advice I have that I think trumps everything else: Get MRI imagery. Without it, everyone is just guessing. With it, you'll have a much better idea of what could make a difference and what just gives your spine time to get worse.
