I guess you have to define "pain." Is it bad enough that you have to take pain killers? I had discomfort (those general zings, tenderness and pulling) for several months. If the pain has increased or if you have fever, you need to call the doctor.
The pain is in my lower back and on the left side where my ovary is. The paint is not so bad that I have to take pain killers but is always there and I have no fever.
