I Have A Slight Cold And I Was Laying Down

I have a slight cold and i was laying down with my right ear against the pillow and was blowing my nose at the same time. I probably blew too hard cause next thing i know, there was a really sharp pain in my right ear. I don't know if i popped it, it just hurts when i move my head. Its like a sharp pain from the inside and i feel like my hearing is a little muffled. Did i somehow seriously damage my right ear?
