Good afternoon, I have been getting the Depo Provera birth control shot since June of last year. But I have noticed that on my left arm, there is a indent.. It sometimes gets hot, and painful to the touch. Sometimes I will go to touch it and it wont feel like my skin. I was wondering if this shot would cause it if given one too many times in the same arm?... Help me!? I am concerned about either keep going with the shit, or pick a different birth control method?..
