I've been strength training doing upper, lower, and core exercises on different days. I've had little more than delayed onset muscle soreness which goes away in a day or 2.
Today was the 3rd day with these particular core exercises, and I had a sharp muscle pain 2" to the left of my belly button and 3" down toward my hip when I tried to do my jackknife on the ball. (lowering back to parallel with the ground is when it hits.) It was sharp enough that I had to stop. I remember a slight twinge on the last set last week when doing this, but it didn't hurt and I didn't think anything of it.
I did the other exercises (mainly lower back extensions and crunches) and then tried the jackknife again. I got through 3 with just a slight twinge, but the 4th was so sharp I fell off the ball. It acted up when I was nearly fully extended on the ball going for full extension. I don't feel it at any other time. Contracting doesn't bother it. When stretching on the floor after crunches, I can feel the left side is a bit tighter than the right, but not at all painful.
My question(s): Is it just the ab muscles that are complaining, or are there others there I should be concerned about? (My understanding of anatomy is lacking!) Will just resting it for a week or so be sufficient? Are there signs to watch for, or are there other things I should be doing? Advil?
Thanks for any insights you can give me.
