I had robotic surgery-endo cysts removed from l/ovary 3 weeks ago. it hurts when im aroused? havent had sex yet it's just when aroused. is this normal?

Not usually: Becoming aroused usually involves some engorgement, or mild swelling of t, he uterus, vulvar organs/tissues, which may be the cause of this new pain. It is not a normal post-op phenomenon. I expect you stil having some internal healing occurring, and rec Ibuprofen (anti-inflammatory) medication for another week or so, and expect this pain will gradually resolve, and it should not persist.

Ovary: I wouldn't say it is normal, but it isn't impossible either. In either case, you are still in the healing period and this will probably resolve over the next few weeks. Nothing to really be concerned about.
