[|Human|] I have a burning sensation that runs from my cheeks down my neck, shoulders, arms to the back of my hands. I also have tingling in the top of my head and a bad taste in my mouth. I get an occasional sting in my eyes. I have stiff muscles behind my neck & on the left side of my neck.
[|AI|]  Hello, Thank you for you question. Based on the information that you provide I think the origin of your problem may be central nervous system that means either you neck or head.in the head there are zones of the brain responsible for all the functions that you mention that are not normal.I would do an MRI of head and neck to exclude any new formation or tumor of the head that may cause these symptoms. If the Head is Ok than I would focus on the neck maybe this symptoms are from cervical spondyloarthrosis or herniated cervical disc that may compares the nerves of the arm or the spinal canal. So i consultation at the Neurosurgeon with MRI of head and neck would clarify your situation.I hope this answer will help you.
