I am just joining this thread, and am pretty desperate for information on this subject. My story is a long one, but to keep it short, I have an ovarian cyst the presented itself with severe pain and low grade fever last May. It wasn't until two months later that it was actually diagnosed as a debris-filled cyst (due to lack of insurance) by way of pelvic ultrasound. Everything that I've read suggests that cysts are worrisome when they don't resolve themselves in 1 to 3 months, but I've been aware of this thing for going on 7 months. It's been almost 5 months since the ultrasound that revealed it, and I know that it's still there because the pain persists, although I have no idea if the size has increased or decreased. What I'm wondering is whether or not it is common to have a cyst that lingers for so long?
