text: Ask your doctor to check ALL of your hormone levels. Your body releases hormones all the time...it's just about the only constant in the human body. So that's where I'd start. Then you can try allergy medicine...could be sinuses...If there would not be any drug/drug contraindications, next sign of a headache take Benadryl. If this works...it's your sinuses.Whatever you do be persistent and DO NOT let your doctor treat you like a "head case". Pain is real whether the doctors know the reason for it or not!
