Why is my left foot freezing but my right foot normal Am I dying?

NOT MEDICAL ADVICE

your left foot may be asleep or you could have just put it in a bucket of cold water or it may also be a symptom of Raynard's phenomenon.

this usually happens in male adults after the age of 35 (not to say it cant happen to others)
