Early labor

I'm now 35 weeks and 3 day. At 33 weeks and 6 days I went into labor. Back,labor! Worst of all.they gave me two shots instead of one to stop my labor cause the first shot did not work.almost 48 hrs later we was back in labor and delivery once again. This time the labor stopped on its own. Im constantly am in pain 24/7 nothing helps ease the back pain. I've barely dilated. But now my stomach is numb all over and has been since I was givin those shots. It could be unrelated also. I'm not sure I just know after leaving the hospital I noticed my whole stomach is numb. You can poke my belly with a little needle and I won't feel a thing. I have an appointment on Wednesday and I'm going to,see about it then. Has anyone else ever experienced any of this? This is my 3rd son(child) and this is the first time experiencing any of this.
