I'm 3 months PP with my second child and 31 years old. I'm very active, don't drive so I walk everywhere. Since I gave birth my ankles ache and get stiff and need cracking every few minutes, and my other joints are so stiff that I seize up when I get up from sitting down, like an elderly woman.
I didn't put on any extra weight of my own in pregnancy - I'm the same weight now as I was before I got pregnant (not boasting; still very overweight - thyroid issues mean I don't lose or gain weight) so I don't think it's down to that.
I'm exclusively breastfeeding, if that makes a difference. Is this to do with relaxin? I'm tired of feeling like an 80 year old and wonder if I'll ever feel back to normal.
