birth control
"I had the nexplanon for a year and two months. It was an effective form of birth control until it started giving me excruciating joint pain to the point that I could not get out of bed. It started with the bottom of my feet and my toes. At first I thought I had hurt myself working out or some problem with my feet. Two days after that it started in my fingers and then day after day it started working its way to my wrists, elbows then shoulders. Then it started moving to my knees. The inflammation and the pain grew tremendously. This was all in a month. During that month I went to several doctors. None of them knew what it was. It sounded like RA But I did not have any of the symptoms that would lead to arthritis."
