Ladies, after I had my son, my tail bone (butt bone) whatever you wanna call it, has been hurting me like hell since I had my son 4 months ago. I didn't get the epidural I did all natural.. any advice? What's wrong? Or what can I do to make it stop hurting me? 😭😭😭 or do I need to take this to a doctor
