Do they cause a pain that wraps around from the small of your back and extends down the front of your upper leg muscle (rectus femoris).
I don't need to be told to see a doctor. Last time I did I had a load of invasive tests (no man should have a camera shoved there) and scans and was told I didn't have any - only to pass one a week later.
I'm more interested in if the leg pain is associated with kidney stones. I've read that the pain can extend into the groin area, but mine is definitely running down the leg (a bit like a pulled muscle).
