Sudden sensation of heat in left foot

[pjmporter]

I recently began experiencing a sudden sensation of heat in my left foot.  I comes and goes several times during the day.  There is no pain with it at all, but it is worrisome.  I don't know whether to wait and see if it goes away, or consult a doctor.  Has anyone had this strange symptom and been able to find out what it was?

There are nerve receptors which are receptive to : cold, heat, pain etc. So there is something which is irritating your receptors which is causing heat. The most common reason is local allergy or irritant which is causing. Try some anti histamines if it does not help you have to visit a neurologist. Take care!

I do not understand what kind of allergy or irritant you are talking about.  I know what anti histamines are and how they work, but what would these have to do with nerve receptors that travel to the foot?  I appreciate your input.
