Yeah, I get numb every once and a while. If I get my hands on some mad dank, I'm usually feeling numb all over. Mostly my legs, sometimes my arms, and even my entire head. So yeah man, I definitely know what you're talking about. You're not alone. Getting that numb feeling is amazing. I love it. When it happens I usually just close my eyes and let it just sooooak in (because it usually doesn't last very long). Cherish that shit, man. It's beautiful.
