What Causes Painful Calves And A Feeling Of Warm Water Poured On My Feet?

I have achy calves and feet and a sensation like warm fluid is being poured down my leg into my feet. I have also noticed recently that my chest is heavy and my pulse rate is slower [56] i also sometimes have the odd palpitation when i'm laying down. I gave up smoking 8 weeks ago [have not been using any nicotine replacement]
