Hello. I have suffered from either menstrual migraines and in the past few years, it has switched from that to ovulation. The pain comes on the same day every month. Sad part is, I don't have insurance. My state has not expanded Medicaid, I cant go to a doctor, have no money and anyone who can help me go. I get suicidal sometimes when I have the pain because it is quite painful. it lasts for twenty four hours usually and by then I can take Excedrin to fix it. anytime before then and it wont work at all not even in the beginning when it first starts. it might delay it for a few hours but that's it. I get nauseas and its just the most horrid thing. If anyone can help tell me..Thanks for listening.
