What Is The Cause Of Swelling And Itching In Forehead And Scalp?

Hi, may I answer your health queries right now ? Please type your query here...i am a 28 year old female. I woke up two nights ago with a swollen forehead area that went from my scalp to right above my right eye, it also was itchy right above my eyebrow. The following night i woke up and it had moved to the left side of my face in the same area and has causen my left eye to be swollen as well (there is no longer any swelling on the right side of my head anymore though) i am 11 weeks pregnant and this is the third time i have woken up with swelling on either side like this.
