Top of thigh goes numb

[KL Aguilar]

I am a cervie, with C3-7 disc damage, especially at C5-7. My symptoms have always been located in my arms, hand, and shoulder blades, but one or two times a year, I've had muscle spasms through my entire back. MRI and X-rays show nothing significant in my lower back.

For the last month or so, I have been getting brief episodes where the top of my left thigh goes numb. By top, I mean the area closer to the surface, facing up if one is sitting. This has happened when I was standing, sitting, and lying down (face up) and does not seem to be related to position or activity. It feels very weird but does not hurt.

My question: is this a cervie symptom that others have? Or???
