<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have already been diagnosed with peripheral neuropathy. I take Lyrica and oxycodone , xanax and trazadone. Lately for the past 2 mos. I have been falling and have had electrical feelings in my head but they do not hurt . The electrical feelings started 3-4 months ago and now are every hour and I cannot work. I can hardly stand to type at the computer or think. I have a metallic taste in my mouth and things do not smell the same. Also I have no appetite.  <response>: Hello! Welcome on Chat Doctor! Regarding your concern, I would explain that your symptoms seem to be related to trigeminal neuralgia. But, considering the loss of smell, I would recommend performing a brain MRI. Some other tests are needed to exclude for the causes of peripheral neuropathy which could also explain the lack of smell: - complete blood count for anemia-iron levels for iron deficiency-vitamin B12 levels-thyroid hormone levels - fasting glucose and HbA1C for diabetes Hope you will find this answer helpful!
