Needs re-evaluation: See your treating dentist. Root tip may be infected or the tooth may have a fracture. Needs to be tested and visualized to know for sure.

Normal, no?: What you are describing is not normal, but whether or not it is a simple fix, such as a bite adjustment or something more serious requires a one on one evaluation with the dentist who treated that tooth. Call and request an evaluation.

Wait: Pain you have is not uncommon after Root Canal Treatment , and should be subsiding next week or two. Let your dentist know in case It is getting worse or staying longer.

Reevaluation: You may have residual infection if auxiliary canals were not fully obliterated. You may have fracture of the tooth. Return to your treating Dentist or specialist Endodontists for reevaluation.
