Oh yeah! I've had joint pains before diagnosed, and now after my TT I feel like I have the flu..without having the flu. I had severe hip pain (lower back, to hip sockets, to knees, to ankles), especially during TOM...think labor pains. I found out that my vitamin D was extremely low, and take 100,000 units once a week now..with a daily 2400 calcium/vitamin D. It is a bit better, but I'm thinking it is/can be a combination of vitamin D and hypo..or either or.
