Pain after wisdom extraction is normal and for some it does take longer to recover then others. From how you are describing your pain it seems more like a jaw pain then pain from the extractions. This may be because of having your mouth open for a long period of time why the did the extraction. Sometimes because of that your jaw can hurt for a longer period of time.
As for it being dry socket. From my understanding dry socket would be very painful, since you are exposing a nerve. So off hand I would say you may not have to worry about it being that. But go see you dentist anyway have him/her confirm what the real issues are so that they can treat you for it.
