Weird soreness from Deadlifts ?

[awds]

Every rep i did today, gave me a weird soreness in my upper/middle back(kind of like you feel it in your bones). I still finished a couple of sets, but i didnt use heavy weight. Could this be a sign of overtraining ? Week before i Deadlifted 30lbs more then usual, and squatted 30lbs more then usual. and my leg and back days are 3 days apart.

DL's target your erector spinae muscles which run parallel to your spinal column. How often have you done heavy DL's, and also what style of DL's were you doing...(Conventional, Sumo, Romanian, Dimel, etc..) Were you doing the same style DL's today that you did last week?

Are you positive that your form is good? When I first started with deadlifts...my form was 'ok' at best and I was getting pain in my back. My form still needs work, but that's probably the first thing to look at.
