Losing feeling in my face?

I woke up this morning and my cheeks are difficult to feel, like MUCH less sensitive than say my forehead or any other part of my body. I can't still feel them, though. This started on my nose. I use lots of different acne and general skin irritation treatments, like Clear & Clear sensitive skin astringent, hydrocortisone, other ones, Clear & Clear spot treatment, Aveeno lotion, and i wash my face with Cetaphil everyday. Could this be a part of it? What do i do? Is this serious? Because i was reading online and it say that it was early symptons of MS! :( My family doesn't have a history of MS though, just heart trouble and diabetes. And bad skin. Could it be a pinched nerve? Help me please!
