What Causes Swelling In The Left Side Of The Face?
Go to ER as soon as possible...
Swelling in the face, even partially can be due to :
- local trauma
- skin infection
- mouth/teeth problems
- contact dermatitis
As you do not own a XXXXXXX phone to send in a photo, and if the swelling is as spreading, I highly recommend to go to ER as soon as possible.
Immediate diagnosis and treatment is required to prevent further spread.
Hope this helps.
