In a recent study of men and women with carpal tunnel syndrome (CTS) pain level was not able to diagnose or predict a CTS problem. The same measuring tool used with you was used in this study. It's called the visual analogue scale (VAS). Three ratings were given:
worst pain over the last 24 hours
least pain over last 24 hours
current pain
Each patient had the nerves and muscles tested for CTS. Although pain wasn't accurate in predicting who had CTS, there were several other tests that were helpful. One of these was the flick test. A positive flick test occurs when pain and symptoms go away after shaking the hand(s) as if to shake down the mercury in a thermometer. Age over 45 and being overweight are also good predictors of CTS.
