Mrs DTR has this in her hands (it does only seem to effect one of her hands) she always wears gloves when it’s slightly cold and also puts those disposable hand warmer jobbies inside a pair of convertible mitt/ gloves when it’s especially cold which seems to do the trick, her hands still get cold and she does sometimes hit me with the freaky cold hand of death when we’re driving back from running club but these have definitely helped, she doesn’t have issues with her feet but I do know that you can get foot warmers, not sure how practical these would be though
