Hi there im a 34 yrs old, awaiting to have a Lap op to remove suspected endo in ovaries. Im very worried and in 2 minds to go ahead with this op. I suffer with very painful heavy periods that can be very clotty. I have shooting pains down left leg during heavy bleeds and feel very tired all the time. I have had 2 scans and 1 internal camera prior to op date, the 1st scan revealed a cyst 2cm in left ovary. the 2nd scan the cyst had grown to 4cm. An internal camera was then advised, by this time the 4cm cyst had gone and instead I had 2 small cyst on either ovaries. If these cysts go naturally, why do I still need surgery?? Can someone please help me make the right choice.
