The test is a good idea. Cannot hurt to see what it shows. I have Carpal T. in both wrists but I have tried hard to not have to go the surgery route. I do wear the braces with the metal pc that goes up your palm. It helps. But I cannot cross-stitch for very long or handquilt for a long time. I have to time myself or I pay dearly. My DH had the surgery & he has done wonderful. If mine gets to where it is unbearable I may have to have the surgery. Ice & the braces are working for now. And shorter periods of hand stitching.
