I have been on Aviane for 12 days now, and every single day I have had a headache (except for one day) with severe pain in the back of my neck. My normal personality is how others described theirs on this birth control, so I haven't noticed any changes in that department. Just 2 nights ago I had excruciating pain in both my wrists, my right knee, and my back for no apparent reason. This pill has already started slowing down my EXTREMELY heavy periods, and I am very grateful for that. It has given me acne which is rare for me. I usually have clear skin.
