Hi, I am a 30yo female, on day 5 of my period. Since day 3, I have been having flu-like symptoms. Nausea, muscle aches (shoulders/neck area and especially lower back/hips) I have been vomiting intermittently, as well. It s bad enough that I can t sleep without taking a muscle relaxer and even then, only for a couple hours. I believe it has to do with my period because the nausea abates a bit when I place a heat pad on my abdomen. Anything you could tell me would be a godsend. Thank you.
