What Causes Tingling Sensation In The Left Forearm?

default
Posted on Thu, 12 Oct 2017
Question: Hello! When I turn my head to the right and slightly down, SOMETIMES I get light-headed and "gray out" for 1-2 seconds. On RARE occasions (it has happened 3 times in the past 6 months) my left forearm and hand will tingle. Yesterday, along with the "gray out" my knees began to buckle, and then my arm tingled.
What would cause this? My dr and I have ruled out positional vertigo. Thank you! XXXXXXX

Brief Answer:
cervical disc disease?

Detailed Answer:
Hello,

neurological symptoms on the upper extremity can be justified with cervical disc disease. For example a slipped disc may exert pressure to the nerve roots that supply sensory fibers to the extremity. The knee symptom is a little unusual, I can't explain it... Perhaps faintness was the cause.

Radiological testing may identify stenosis in the cervical spine. MRI scans will provide more details.

I hope you find my comments helpful!
Kind Regards!
