I had a blister come up on my cheekbone under my right eye the other night, it was gone within 2 hours, tonight I have another one come up, same place but under left eye this time, twice the size. Entire cheek is very warm to touch and blister area is itchy. Am on no medication. No allergies. Do suffer from psoriasis and IBS though. It doesn't look like psoriasis, it looks like a water filled blister. It's already going down again. Just curious as to what it might be.
