Try An Electric Throw. It Is A Small Electric Blanket And You Can Wrap It Around Yout Legs ... It Is Good Because The Parts Of Your Legs That Have A Good Sense Of Feeling Can Let You Know If The Temperature Is Right For You. I Keep One Near My Computer Because This Room Is Cold.
I Also Use Fleece Socks All Winter.
And Last But Not Least Sit With My Feet Near The Wood Stove ... That Is The Best Type Of Heat.
And As For Your Doctor, Please Remember, He Works For You ... And Has No Right To Be Rude.
