"age: 24; births: none; previous contraceptives: none; i just got mirena inserted yesterday with no anesthesia. i took 800mg of ibuprofen before my appointment. i experienced two sharp pains that lasted ~10 seconds each--one during measurement and one during insertion. i just tried to relax my bottom and breathe through it. the pain immediately subsided after she inserted the mirena. i did feel crampy for the rest of the day, but i returned to work and even went to the gym and did a 2 mile run on the treadmill. so it wasn&#039;t terrible. 

i can only comment on the insertion experience since i just got it inserted yesterday, but hopefully this will be helpful for those of you who (like me) are feeling anxious about the insertion."
