What Causes Hypersensitivity Of Face And Drooping Eyelids?

hi, i have been having this sort of hypersensitivity on my left side of the face. it started with the upper part of the face to the cheek, then after a while from the cheek to my jaw... now, i felt that my left eyelid is somewhat drooping. this has been for almost a month now. i was exposed to chicken pox and i am also hypertensive though the feeling on my face is the same even when my bp is normal. i am about to go to have my blood tests tomorrow. It sometimes goes away then returns and come backs again.
