I understand your concern about "the pill", but they can shrink the cyst usually in a matter of months. This would be much cheaper than having an operation and hopefully not affect your risk of stroke too much. If you don't smoke and are a healthy weight you are probably okay to take the pill for a short period of time without too much risk to your cardiac health. The cyst may shrink on it's own, too. If you are really concerned about taking hormones than I would suggest taking Tylenol and giving it a few months. Make sure you check back with your doctor. Good luck!
