Pains while squatting...

I have been weight training for a few years and today is the first time I experienced sharp stabbing pains.

I was mid squat when I got the sharp stabbing pain half inch to the right of my belly button. I paused when I was up and it was ok, I took a breath before my next rep but the second I tried to squat it happened again.

I gave myself about 3-5 minutes and went back to my reps and was fine after that.

Anyone else experience this? I've experienced other pains over the years but this one was weird to me.
