I was the same, fit and healthy, think I did the damage through heavy landscaping.
I think the worst of it will fade fairly quickly, but you may be left with lingering symptoms for a while. I never had excruciating pain, mine was always some pain but mainly nausea / dizziness. Had an MRI on my insurance, as they thought it could be a possible Syrinx, thank Christ it wasn't.
No surgery, just prolonged discomfort. Didn't take any time off work in relation to it, but often felt very unwell. The body is very good at healing these things over time though, thought I'd have to live with it forever, but had been much better over the last few months. Good luck, and get an MRI if you can. Very worthwhile.
