Hey. I had my d&c yesterday. Since i got home in the evening, i've had this uncomfortable back pain/ache. I was told to apply a cold compress and take acetaminophen. Well it's been more than 24 hours and it's still bothering me. I didn't have this with a previous d&c last year. Have any of you had this? What else can i do?
