Endo, ovarian cysts, and castor oil packs

Michelle • 34, DH 37. ttc #1 for 4+ years
Has anyone with an ovarian cyst ever used a castor oil pack and had success with it dissolving? In July I had an US and the doctor saw a 3.7cm cyst hanging off the bottom of my left ovary. This month I had another US and it was measuring 4.1cm. The doctor is pretty sure it's a follicular cyst, but what concerns me is that it hasn't resolved and it's been 6months. It does cause me pain every month, and recently I've started to get sick around O. My Dr suspects I might have endo and wants to schedule a laparoscopy, but I'm hesitant to go under the knife for something I don't think I have. I really think my pain is from the cyst. I was also thinking about trying acupuncture before making any decisions about he surgery.. Any insight anyone can offer would be appreciated. Thanks ladies!
