Every month right before my period and during for like 2 days I have a pain on the back right side of my neck and the pain spreads to base of skull, then my face hurts like I have sinus issues. Even the front right of my neck hurts, then the pain upsets my stomach and sometimes I throw up. I see a chiropractor about other neck problems once a month and usually my atlas is out so he pops it back. These other problems, could there be something wrong with my pituitary gland? This has been going on for years. I try to eat green apples, celery, drink grape juice the week of my period. I take Omega 3,6,9, evening primrose oil, vitamin D a week before. I ve started to add calcium and magnesium to see if that helps. Sometimes the symptoms are light but other times it hits me full force. :( Thank you for your time!
