I am a 31 year old woman and have just started getting awful head-aches on a daily basis. The pain runs from temple to temple across my brow-line. My eyes ache severely and I feel I have to shut them. Normal head-ache tablets make no difference. I have a contraceptive implant in my arm. Could this be a side-effect? What can I do to relieve the awful pain? Having 5 children, peace and quiet is scarce!
