"i can&#039;t speak for long term however i just had the kyleena inserted today. i took 600mg of tylenol before my appointment which helped a lot. the insertion didn&#039;t hurt as much as these reviews led me to believe. it was just uncomfortable and a little crampy but not bad at all. i&#039;ve had it placed for about an hour and i just have minor cramping, i will update after i&#039;ve had it some time longer. i would recommend this birth control method."
