Why Are My Feet Purple And Numb?

Question: My feet are purple and numb and at times I have horrible pain that seems to radiate from behind my knees. If I drink water I swell. I did have my heart and circulation check by a med. group that travels around. They said everything was fine and I have slight plaque build up. This hit me about a year ago . I am almost 60 and not ready for this slow body moving body.

I am not taking medication at all. The levothyroxine made me feel horrid plus it is not in my budget to see a Dr. every 3 months for evaluation and lab draws. I feel better with out it. My Dr. said it was slightly off and I remember in my twenties it was slightly off. I do smoke from 7 to 12 cigs a day. It started with the left leg swelling to the knee and has gradually become both feet. The purple is not related to temperature. They do feel cold. I feel like they are going to crack open like my skin is dieing. If I put them in warm water they turn bright red. Numbness never leaves. I think the best they look is when I first get out of bed. I have massaged them and if it is vigorously done they will loose a bit of the purple. Pain is random ..very sharp and lasts anywhere from 5 minutes to 30 minutes. The feeling after the pain leaves reminds me of a deep bruise. Many times I spend the rest of the day with XXXXXXX horses. I feel dehydrated because I have not been able to take in the water I am use to. I try to drink a quarter cup every hour. I was accustomed to almost a gal a day. Oh one other thing.... When this first started my big toes want to stick up! Crazy!
