I know this is a super old thread but I suffer from it also. It just started less then a year ago after turning 35. The week or so before and during are horrendous for me. Headaches, anxiety, dizzy, moodiness, chest pains, can't sleep, etc. Then I'll have a good week, maybe two before it starts all over again. It sucks. I am thinking of going to my GYN and possibly getting a referral to endocrinologist or hormone specialist. Not really sure who to see.
