Postpartum healing

I had a third degree tear as well as an episiotomy.

I know it will take some time, but is it normal to still feel very tender, sensitive and sore 3 and a half weeks postpartum?

I clean with the peri bottle everytime I use the washroom and only very lightly pad dry with toilet paper, and it still hurts when I sit on hard chairs.

When will it start feeling better?
