Constant tingling in my left ankle. nothing hurts. not aware of any injuries. sometimes feels hot inside as if the blood is only just getting into it?

Need more info: I will need more info from you, any medical problems like diabetes can cause tingling / burning. See a doctor, in the interim try Vitamin B .

Tingling: in the joint area can be a sign of a variety of things... nerve compression can cause it as well as arthritis and any post-traumatic injury. If you are concerned get an exam done for the proper diagnosis and treatment if needed. Best wishes!
