Snookums:

To be honest with you, I know how you feel , sort of. When I had panic attacks, my legs would go numb from the knee down. I don't think it's a weird symptom, I really think it's a common symptom in people who do have panic disorders/attacks. I've heard of it several times from others who also have panic attacks that something goes numb, maybe arm, maybe hand or legs like mine do.

I hope this helps!

Take Care of yourself,
Kimberly.
