I am 25 and they found a 11.4 cm simple ovarian cyst on my right ovary. I have spoken to two NPs and one gynecologist. The first NP was concerned and said that I might need surgery. The second NP who specializes in obgyn tells me to monitor the cyst and get another ultrasound next month in September. My gynecologist says there is nothing to worry about and that it will resolve on it's own and will follow up in a year. I'm confused by everybody's opinion. I'm not sure what step I should take next. Does a 11.4 cm cyst usually resolve on its own? Recently I have been feeling dull pain in my lower pelvic area where the cyst is located and also in my right thigh.
