There could be many things causing this from systemic, like bad nutrition or anemia, to a neurological problem. You need to see a doctor to run some tests. PLEASE SEE A FAMILY PRACTICE DOCTOR to run some blood tests for a start. They will refer you to a specialist if you need one. ONLY A DOCTOR CAN DIAGNOSE YOU.
It could be a blood sugar issue, or a neurological issue or even a circulatory issue. Have you been to a doctor yet?
