birth control
"My arm was sore for 3-4 months after I got it.  Whenever I tried to carry my wallet against my arm it hurt.  Anything rubbing/touching my arm hurt for months.  I would not recommend this.  I just got mine taken out after using it 1 yr & 2 months.  This pain will just teach you to suck it up and remember to take your pill each day.  Normally I don't get periods on any kind of birth control but with this one I got my period every 2 weeks for about 4 months.  With this med you do retain water, so you are going to gain weight and I felt hungry all the time. Just doesn't make sense to get cut, put a hole and your arm for birth control.  I have also tried an IUD before this one, no foreign objects should be used in your body.  Don't do it."
