Injured back from deadlifting, do need to go to the doctor?

A couple of days ago i injured my back dead lifting i was fine straight after and in the morning the next day but gradually the pain became really bad. If i walked about i found it almost im possible to sit down after. Ive been putting ice on it for the last two days, as soon as i get home from work i have to lye down. This morning i found it impossible to get dress for work so i have to stay home. Im not sure if i will feel any different tomorrow so should i go to the doctor today?
