Could my mouth severely swell from eating potato chips/crisps?

I’m a bit afraid. I RARELY eat crisps. Last night was anxious and uncharacteristically, ate a LOT right before going to sleep. I woke up this morning to severe facial swelling around my mouth and cheek – the side I chewed on! At first I thought I had a stroke – it was so scary. But no “drooping” and everything moves… just very swollen. What could this be?
