Hello and thanks foe query.
Prima facie it looks as if your food was responsible for this swelling and numbness.
However there can be few other reasons which should be explored.
Did it happen to you for the first time?
Is there any ear blockage on left side?
Do you have any sinus problem?
Have you lost any control on the face and is the face drooping?
Are there any excessive tearing on that side?
Is there any history of recent trauma on head?
Once the answers for these questions are known,the diagnosis can be narrowed down.
Thanks
