I've been doing battle with hamstring pain/spasms in my left leg since the middle of June. Mine are awful - the hamstring gets really painful mainly when I'm standing still, and it can get so bad I nearly pass out. Everything I've read about hamstring injuries says to stretch gently, to take Advil or Aleve and to use ice or heat.

I did have a mishap on my bike a few days before all of this started - I swerved trying to avoid being hit by a car, then swerved so I wouldn't hit a curb -- ended up unclipping my feet in a rush and tipping the wrong way off a curb, and the bike came with me - ramming the nose of the seat into the left side of my butt. That hurt like none other, and the doc says it might have caused a deep bruise that's irritating the hamstring. I'm getting some tingling in the hamstring area and in my foot, too, so he says another possibility is my back might be the culprit. My back and hip x-rays were o.k., but I do have scoliosis.--

The doctor told me that hamstring problems can be a real mystery. He's sending me to physical therapy which I'll be starting Friday and he's also put me on Mobic, which is an anti-inflammatory. Wish I had some better suggestions - I do feel your pain.
