Hello, A pimple developed just below my left eye two days ago. I didn’t touch it, only put tea tree oil on it. It’s one of those horrible underneath the skin ones that cannot be popped easily. The pimple itself does not bother me, but I would like to know whether it could be causing swelling beneath that same eye? The area (around 2x5cm) beneath my eye is red and slightly swollen. There is no pain when pressed. There are no tears or secretions.
