I have a pair of merino wool gloves from Isadore for winter/cooler weather riding. They have no cushioning and if I am out for a 100k ride, my hands can start to get sore around the 60~70k mark.
I think what happens for me is that when I ride without gloves, gripping too hard instantly is uncomfortable, and I can feel the bars firmly in my hands without the death grip. With the gloves on, I neither find the squeeze uncomfortable nor can I tell that my grasp is firm. By the time I realize I've been white knuckling, my palms are already sore.
I realize this isn't a universal, but I think it's what OP's doctor was suggesting was happening. I'm curious if OP has tried the no-glove thing yet.
