So this is baby number 2 for me and I'm only 18 weeks and I'm having horrible pain near my tailbone. It is only at night and I can't walk, and when I lay down and I move ever so slightly it's a sharp pain and it feels like if I move anymore it will make me pull a muscle. Past couple of nights i have been using a heating pad for a couple of minutes and it gets better but now it never goes away. I can't move without a massive and sharp pain in my tailbone area. What can I do? Suggestions? I don't remember having this much pain this soon in my first pregnancy. Anything helps
