### input:
A week ago Monday I went to work and felt fine. A few hours later I started feeling very nauseated and chilling and then on fire. I started having severe nerve pain from head to toe. The pain was so intense that I would gag and dry heave. I went to Dr and they did a full blood count and auto immune count. Everything came back as normal. They put me on anti viral meds as to treat me if I have shingles. They also gave me Neurontin for the nerve pain. By Wednesday and Thursday I felt much better. Then yesterday I woke up and was on fire, today is much worse. I have numbness in my head and face down thru my tounge and entire body. I have had constant nerve pain all day that will not go away. It feel like I am on fire . Please help.

### output:

Hi, Thanks for writing in. It appears that there might be a condition involving the nervous system in your body. All the above symptoms like balance, numbness and tingling, headaches and spots in front of eyes are all associated with conditions of nerves affected in various regions. This can be due to an acute cause like shingles which is a viral infection affecting the dorsal nerve ganglion in the spinal nerves or due to chronic problems like neuropathy associated with diabetes or autoimmune disorders. History of any other medical conditions and medications that you are taking is important. Vitamin deficiency states can also appear as non-specific symptoms as described by you. However, this is less likely as you are having sudden variation in symptoms. Please consult a neurologist and get a complete neurological examination done. If there is sudden worsening of symptoms then you might have to go to the ER. Investigations like MRI scan brain and spinal cord might also be required for you. Please do not worry.
