It's not that. I have hyper mobility, which gives me minor aches and pains at my joints, but estrogen has made things a little worse for the time being. It makes my ligaments more flexible and my muscles atrophy if I don't use them a lot. It's not a problem as long as I stay active and don't sit at a computer with bad posture; it just amplifies the discomfort if I don't treat my body right. In a way, it gives me more motivation to be healthy.
