But you first need to make certain that no medical problems are present. If you are worried that your PMS symptoms may be out of the ordinary, do yourself a favor and have it checked out by a doctor. Now I get pretty severe cramping for a day, and then feel generally sick for the next day. I realize that this is minor compared with many women, and that symptoms worsen with age, but I've also experienced a signficant weight gain over the past 4 years. It's possible to have both PMS and menstrual pain but they should be evaluated separately.
Common problems can occur commonly.
It's unlikely that the extra weight is the cause of your problems. Once I stopped eating non-organic dairy products, all premenstrual breat tenderness disappeared. Many women find that eating a healthy diet such as what you are describing is helpful and it's a good way to begin self treatment. But you should always discuss your symptoms with your clinician as well. In the modern world, women have extremely harried lives often with jobs, house responsibilities, and children.
