Hello,
You have a past history of smoking and sinus problem. Presently you are having burning sensation and discomfort under the ears, chin, neck, back and also throat. Since you have sinusitis, it can cause
facial pain or burning sensation. You should get a repeat clinical examination done. Get X-ray PNS done, get treated(by medicines or surgery) at the earliest. Other medical conditions that can cause similar symptoms are developing nerve disorder,
trigeminal neuralgia,
occipital neuralgia, temporal
tendinitis, etc.
Get clinically examined by a
Neurologist / GP, get MRI done to detect the pathology causing you discomfort. Get treated at the earliest. In the meantime avoid addictions if any, maintain your blood glucose level and other vitals, stay active. Maintain healthy BMI. Take food rich in vitamin B6, B12, Vitamin E, proteins and iron, calcium, etc.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
