I am on the depo provera contraceptive injection. I have had pains in both my breasts for months! At the same time I am also suffering with frequent headaches, pains in my arms, pains in the side of my neck, and at times I get a bit breathless. I have also noticed purply/red spots on my legs, I have had them before, they faded away and now they've come back. I also occasionally get backache. Any idea on what this could be?
