C-secrion incison raised?

My incision is raised/puffy not red or hurting at all just raised. Its the whole thing.. i had my c-section done 4 days ago, is this normal? Will it go down over time? Its not the skin around it, its the actual incision it was like this at the hospital and they said it looked okay..

Sorry for posting in this group i dont know where else to post it..
