Brief Answer:
Not likely to be anything life threatening if CT is negative

Detailed Answer:
Thank you for your return question and kind comments of my identifying your symptoms with some accuracy.

Given the fact that the CT scan is negative then, there are no masses, tumors, aneurysms, etc. that are causing these symptoms. Therefore, I would say the chance of this being life threatening in any way is very very small.

I believe that your best move (as I stated in my other response) is to see a neurologist who can perform a good CRANIAL NERVES examination and determine whether this constant and now seemingly chronic pain which we might refer to as a PARESTHESIA of some sort could be due to a peripheral cranial neuropathy or if something in the brain could still be responsible. For that I would likely want to send you for an MRI with gadolinium contrast. Recall that MRI images are about 10x more sensitive for abnormalities than CT scans.

The neurologist can also review the labs you had done to check that indeed the numbers are satisfactory and the types of testing obtained sufficient for your condition.

The neurologist could then, decide to treat you either with medication or something else such as alternative non-pharmacological treatment options if appropriate. Options I consider in my patients who have chronic paresthetic pains in the face or head which are not due to identifiable organic causes would be things such as acupuncture, biofeedback, Transcutaneous nerve stimulation, THERMAZONE therapy, etc.

Medications that may help to reduce your symptoms could be things such as gabapentin, pregabalin, carbamazepine, baclofen, lamotrigine, nortriptyline, and others. Again, choice of drug and dosing are highly dependent upon what is found during the examination and also seen on any further imaging studies obtained and any further laboratory studies that may be obtained.

Cheers!
