I have posted a few times over the past few days about this sort of PMS feeling I have been having for the past 3 weeks . . . mild headache, mild stomach problems, sore lower back and general "off" feeling. What I have noticed is that I am not bothered at all when I am sleeping. It is not until I stand up, and my weight shifts, that the back and stomach start to hurt . . . and then within a hour, my headache comes. Wouldn't you think that if I had some issue with an internal organ or something that I would feel the discomfort all of the time, even when laying down? I am trying to put my mind at ease that I don't have something else going on. I have had multiple pelvic ultrasounds in the past 3 years for similar symptoms and all have come back clean . . . but every time these symptoms return they are a little worse and I am always worrying in the back of my mind about what could be causing them.
