Hi Stubear,
In September 2015 I had a similar incident. Early afternoon, waist high ultra relaxed sup surf and suddenly I felt kind of electric discharge through my spine and a feeling of disconnection/instability between upper and lower back. Immediately my back got locked in a kinda 155? (180? being standing up). I got myself and the gear out of water with enormous difficulty.
That evening, If I was seated in a proper position, I would forget I had anything wrong. If I tried to move, the pain returned.
Day after I had physio massage which helped a lot for the contracture. This was the short term.
Fast forward, I went to the GP,orthopedist and finaly to a neurosurgeon.
I had CT scan and later a MRI (which is much more adequate for this diagnosis). The root cause for this incident was a pinched nerve by L4-L5 bulging disk.
It has been more than 1 1/2 years since the incident and it never repeated. But a lot of big surf wipe outs did :).
In the beginning I was afraid I could not do SUP anymore, my most beloved sport. But later I found that was not the case.
My lower back are still a issue that requires daily attention. My strategies /advices are:
- There are plenty nice clips in YT teaching exercises for lower back pain. Learn a few. They work.
- Check out "Foundation Training".
It really works!!!
- Move. Walk, run lightly, whatever. Being sedentary is the worst thing one can do. (My job is mostly being in a desk in front of a computer).
- I stopped using my race sup for anything but small wave surfing. I prefer to save my back for my favorite part of the sport - wave riding.
- I returned to longer boards. Too short paddles and tiny boards can stress a lot.
- I became more aware of my paddling posture. Watch your stance.
- Always do an adequate warm up.
- Finally, just in case, I researched a plan B. I know it's quite effective and minimally invasive - Intradiscal Ozone Injection for Disc Herniation
