Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
There are multiple reasons one may tingling. Since your symptoms are in the hands and face, causes such as multiple sclerosis and even stroke should be in the differential. Do you have any other symptoms such as weakness, specch/vision changes, etc? If your tingling is moving around from one place to the other, then you may need to be evaluated for seizure, migraine, and even hypocalcemia. Also, often these symptoms may reflect emotional/psychiatric problems related to stress (what is called somatization disorder). The latter is a true medical condition whereby instead of a patient experiencing depression or anxiety, they experience physical symptoms, and once the stress is addressed, the symptoms resolve.
These are just some causes of burning/tingling. Continued follow-up with your doctors is recommended. Evaluation by a neurologist, if you have not already done so, is recommended. You may benefit from an MRI of the brain depending on additional history and examination.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
