I'm almost 3 months post partum and have been experiencing joint pain and stiffness especially in my fingers/hands, toes/feet, ankles. My legs, feet, and hands also get tingly and so does my upper back. Anyone else experienced this? I've read that it could be a hormone imbalance, caused by prolactin from breastfeeding, vitamin deficiency, but nothing conclusive. I'm setting up an appointment with my GP next week but wanted to know if anyone's been through this.
