32 weeks with pelvic pain

I'm 32 weeks along. I have what they believe to be an i inguinal hernia on my left side that I actually had with my previous pregnancy. ( my youngest is 16 months) I also have trouble with pelvic separation that started 2 pregnancies ago. On top of all this I have horrible variscosities down there. When I was in labor with my last one I had the most unbearable stabbing pain around where my hernia is with each contraction. To the point where I was screaming with tears running down my face begging the nurses to do something. I never had anything like it with the previous two. Now at 32 weeks with this one I have been having that same stabbing pain coming and going but no contractions. And also having horrid pain in my hips to the point where I literally am having trouble moving my legs and walking. Then add cramps to the mix. Called the ob on call last night and they are saying it sounds muscular and that's it. I was wondering if anyone has experienced anything similar to this craziness and could help shed some light on the matter for me as I'm in severe pain and have trouble caring for my two youngest at this point. Any tips are appreciated!
