Im 58 years old.What causes waist pain at the left? Its like a razor blade is being used at that side of my waist, especially when I stand for a long time. I wasn't feeling such pains before now. Thanks

My spuse is 58 years. He's got waist pain at the left side especially when he is standing for a long time. It started about a week and a half now. Thanks.

Besides the normal, seek medical advice, I will add this site,
