"i just had the mirena iud inserted yesterday. even though it&#039;s been a short time i wanted to give some information that i found lacking on the internet to new users. insertion was painful but bearable. i was crampy for about an hour afterwards but after about an hour the most unrelenting cramps started and i was in so much pain i was sweating and had palpitations. i took 800 mg ibuprofen before getting it inserted and took another 800 mg after and got no relief. i used a heating pad and also got no relief. two doses of 50 mg tramadol later (roughly 8 hrs after getting it inserted) the cramps disappeared and i have only had very mild twinges a couple of times today. don&#039;t worry that you&#039;ll be in pain forever; you won&#039;t! it passes quickly."
