I am getting bloo clots in my nerves on foot and day by day it that increasing in both the foots. And also getting heat why?

You aren't getting blood clots IN your nerves. It is either one or the other. In essence, the blood clot Is causing nerve damage and you absolutely do not want that clot moving back up your leg to your heart. See your doctor immediately. He can also diagnose why you feel heat, which may only be symptomatic.
