[|Human|] I had a CF leak due to a tear in my dura 2 years ago. A year ago I started having a burning and tingling sensation in my mouth and hands when I ate or touched something cold, like holding a can from the fridge or when I drank a cold drink or  ate ice cream. Now the numbness extends to my arms, but it comes and goes worsening at night. Three days ago my right leg went numb from hip to toe, not sure what is going on. Any ideas?
[|AI|]  Hi, Thank you for posting your query. The current symptoms are most likely not related to the CSF leak repair, which you had two years ago. However, these symptoms are neurological in nature and need to be evaluated. We need to do a scan of brain and spine (preferably MRI) to find out the cause, such as ischemia (lack of blood flow) or declination (such as multiple sclerosis). In addition, please also get your vitamin B12 and D levels checked up. Please get back with the reports. I hope it helps. Please get back if you require any further information. Best wishes, Chat Doctor. Ly/
