I've had these same strange feelings in my hands and feet for years! When it is really bad it goes up my arms and feet. I've tried to explain it to my doctors as an uncomfortable deep numbness or heaviness but it doesn't quite explain it. I rub my feet and hands together constantly and that makes it more bearable. Sometimes it is worse than others but it has gotten really bad in the last week so I came on here looking to see if anyone else had similar experiences. Although there isn't a diagnosis on here, it is comforting knowing I am not alone and not crazy (or if I am than I'm in good company) JK. If anyone finds a diagnosis, please let us know!
