Ever since I had my daughter 7 months ago it feels like I got ran over by a bus. My feet hurt. Like literally walking on them hurts really bad sometimes, my knee hurts, my shoulder hurts and my back. I know my shoulder and back are from this car accident I was in 2 months ago but I'm not sure if the other is from that. Just feels like I have an old body now lmao. I mean I snapped right back after I had my first daughter a little over 2 years ago. No problems wasnt sore anywhere. I felt the exact same as before I was pregnant. Just worried me in a way because how will I feel like when I'm actually older if I'm having issues now lol
