Hi was wondering if not having a period can cause someone to have a headache everyday or more than once a day. I have gotten headaches for days on end now for the last week and half I did go to my local walk in because I had a ear ache and splitting headache they said I had a middle ear tube problem and they gave me prednisone and told me to take Sudafed and it helped with my headache the first day but I still got them and still get them?
