Despite not having pulled sumo-style in a LONG time I stupidly decided today to see what my max would be. On my final single, I felt a 'pop' in my low back. Now it didn't actually hurt, nor does it hurt now (couple of hours later) and I seem have more or less full ROM. I get a little pinch if I bend backwards into extension but otherwise it's ok.
However it does feel off, like there's something not quite right and I can't work out what it is.
I realise I can't expect a full diagnosis off the internet but has anyone experienced something like this before? Any ideas or suggestions most welcome.
