I didn't feel the tearing with dd, but i oh so absolutely did with ds! it was REALLY, REALLY bad...even though I was in awful, AWFUL pain from the contractions, even that was not all that bad compared to the pain of tearing.....I think it was because the pain of contractions, even though for me it was SEVERE, totally way above 10 on the pain scale painful...it was a different, special kind of pain.....and the pain of the tearing was like.."normal" pain, the kind that signals to your body "something is wrong, bad, danger, pain! " and it was just so much sharper, a very bright, blinding meteor of pain that just shot through the huge, overwhelming, completely consuming, yet somehow deeper, duller, pain of the rest of labor/contractions. I don't know if that makes sense at all if you haven't experienced what I did. sort of like the difference between having a deep ache in a pulled muscle, versus slashing your hand with a knife...it was just a completely different *kind* of pain. i'm a music person, so in my mind, I picture the pain of teh contractions as a "bass" ..a low, deep, very strong, encompassing kind of pain, and the pain of the tearing was a "soprano" note, a high, sharp, bright pain that just tore through the rest like a bullet.
both sucked like hell.
