Small painful ovarian cyst?

Wondering if anyone out there has had a small ovarian cyst cause them pain? I have been having a sharp pain on my right side for weeks now and my ultrasound revealed a small 1.4cm cyst on my right ovary. The doctor told me that should not be causing pain and just sent me on my way with no indication of what can be causing my pain.

I’m wondering if it’s just a coincidence that I’m having pain and there’s a cyst or if the cyst can actually be painful?
