I had a laparoscopy 10 days ago to remove 7.5cm chocolate cyst in my left ovary. I have been diagnosed with endometriosis. I am 29. I was recovering very well until 2 days ago I experienced a stabbing pain in my left ovary, especially in the mornings. Yesterday I started taking hormone treatment that will cause an artificial menopause for 4 months. I feel out of balance and anxious. Is this common? I have a 3-hour flight tonight and I am starting to feel worried.
