clarification - my back pain episodes were 2x in ... about 3 years. in both cases this was a sudden onset - like, standing up from a seated position, some sort of switch was flipped, and I had immediate massive pain.
In both cases, talking to a local "urgent care" clinic, "go to your GP for a referral for physical therapy" was the standard line. "we don't treat back pain".
I get it, in some sense, like... yeah, I may be an addict, etc. But in both cases, I'd been to the clinic multiple times before for other things. I had a history with them. Actually, the last time I'd been there I said I had no primary care physician, and wanted to use them as primary (3 miles from house vs 11 miles to previous dr).
In both cases, the back pain episode lasted more than a week, was debilitating to the point of not being able to walk without massive pain or sleep normally for several days. And then, it wore off, and ... 'back to normal'. Historically, I'm learning, we have some back issues in the family, but I can't get much info from anyone on specifics yet.
