Brief Answer:
There are numerous causes to this symptom

Detailed Answer:
Good afternoon. My name is Dr. Saghafi and I am a neurologist from the XXXXXXX OH region of the world. GO BROWNS! I can see you're located a ways up the peninsula there....does that put you in GIANTS or JETS territory? Probably JETS, no? Well, at any rate...nice to meet you. I've read several of your other questions that you've sent to other colleagues to get an idea of what the other medical issues are that are concerning to you. So I notice that while your feet appear to be COLD and NUMB your ears are HOT and BRIGHT RED.

Let me ask this question. Have any of the questions/problems that you've posed over the past few months been entirely resolved or remitted on their own...or with treatment? If so, can you let me know which problems you no longer suffer from or are much less bothered by compared to before. Also, how long have you had the problem with the feet?

At any rate, allow me to simply list a few entities that could be responsible for cold and numb feet. I'm not necessarily listing them in any order...just as they come to me.

1. Autonomic dysfunction, however, I think this unlikely due to how young you are
2. Hormonal problems with thyroid or adrenal hypofunction
3. Vascular problems with blood flow to the legs and feet in general
4. Neuropathy in the feet either due to nutritional deficiencies such as sodium, B12, folate, alcohol excess, and Vitamin D
5. Along the lines of neuropathy would be many of the CAUSES itself of neuropathy such:

- Lupus
-Rheumatoid arthritris

6. Raynaud's phenomenon
7. Extremely eating disorders such as anorexia nervosa
8. Acrocyanosis (bluish discoloration of the fingers and toes suggesting poor circulation)
9. Congestive heart failure
