I've just recovered from 9mths of mono. i also have a 2cm ovarian cyst. could either (or both) cause terrible headaches that i now experience? thanks!

Maybe mono. : Ovarian cysts are often silent, and when they're symptomatic, abdominal or back pain predominates the clinical picture. Mono can have a long recovery, including chronic headache. Also be aware of tension fatigue syndrome that can follow mono in some cases and can have headache as a symptom. Best to see your doctor to figure this out.
