"i lasted 6 days with nexplanon. getting the &quot;rod&quot; put in was fairly painless. however, a day after insertion, i began to have shooting pains up from the site through my shoulder and neck along with a killer migraine. when i held my hand out, it shook uncontrollably. i was put on an antibiotic in case of infection. a few days later, the pain was still the same and my hand began to go numb even when my arm was stretched out straight. i was so uncomfortable and could not function because of the continuous migraine (it would not respond to any pain reliever). i had my nexplanon taken out and suspect it was placed on a nerve. the hormones most likely caused the 5 day long migraine, so i will not be having it put back in."
