Swelling of eyes and face

Patient: My eyes have been slowly swelling over the past 2 months. My face is puffy all the time and my upper lip seems to be swelling now as well. I have been taking benadryl as I was told it seems to be an allergic reaction. The benadryl doesn’t seem to help. I haven’t had any luck locating the culprit. Is there any other reason this could be happening?

Symptoms: Swelling of the eyes and face, itchy eyes
