Okay ladies I have a question. I have an appointment with my doctor on Thursday but wanted to see if any of you experienced this. I'm 34 weeks with my second child and never had this with my son. I did labor in my back more with him which is why I'm a little concerned. I was sitting down and when I got up I had some back pain in my lower back which isn't a surprise as I have back pains with her a lot. anyways when I started to walk around and get up I started feeling numb on my left side in my arm and leg. I went to get my son and I some milk and make a sandwich. by the time I got done, I was in so much pain that I could barely walk, I couldn't get into bed myself, couldn't move my leg. I literally haven't been in that much pain before. it started in my lower back and is radiating down through my leg. my arm is still numb feeling. I have literally been bawling it hurts so bad my husband tried massaging my leg, hip, and back to relief pressure meanwhile my 18 month is sitting right next to me and so I'm trying not to worry him and freak him out but I have never hurt this bad. any ideas on what it could be or advice on helping with the pain.
