Conversation: The conversation between human and AI assistant.
[|Human|] I have pain in both my inner arms from time to tine and feel thirsty often no matter how much water I drink. I have poor circulation to my hands at night and I had a bad back injury 6 years ago. I have had chest MRI and CT scans and nothing is enlarged. What could this be?
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I went through your question carefully and would explain that your symptoms seem to be related to a pinched nerve in your cervical column. Besides a metabolic disorder could also explain the continuous feeling of thirst. I recommend performing a careful physical examination and some tests : - electroneurography to examine your nerves in your upper limbs for possible compression signs-blood lab tests (complete blood count, PCR, sedimentation rate, kidney and liver function tests, blood electrolytes, blood osmolarity, cortisol and aldosterone plasma levels) and urine osmolarity. You should discuss with your attending physician on the above issues. Hope to have been helpful! Greetings!
