Yeah Mrs.D, my feet do that too. I can just rub lotion on them and when i touch a certain area, it feels like I have a vibrating cellphone in my foot. Sometimes now, the vibrating feeling goes up my shin bone too. I do still feel things when I drop them on my feet and I definitely feel things I step on. I guess some of us loose sensation and some get heightened sensations. To my thinking, probably feeling too much is better than not feeling.
We are all in the same boat

just slightly different.
