Does anyone know about a recent Frito-Lay Munchies RECALL?

I recently bought a bag (ironic since I'm usually staying away from these types of snacks) and had a handful in two settings. I've had these before with no effect but this time I had them and after a minute or so my mouth felt like it had become injected with novacaine. My mouth feels heavy and like I just came from the dentist! I don't think it's an allergic reaction unless they've changed their recipe in the past two years..
