Left side pain

Nouran

I went to the dr a month ago and i found that i have a cyst on my ovary and my right side was hurting me so much, but she told me that it’s okay and not to worry and wait for two to three month to check again, because it’s supposed to go away by itself, but now I don’t feel any pain in my right side, and my left side is killing me, so has anyone gone through the same thing, or know what is going on?
