Anyone else have an internal tear from birth?

Nicole • Mummy of 3💙💙💗 #4 due October💗
I had a second degree internal tear. They did think it was third degree but when they took me to theatre they saw that it wasn't. I'm 3 weeks pp and it's still hurts when I'm standing and walking. It's like really painful pressure. Is it normal for it to still hurt after 3 weeks? I keep getting worried incase something is wrong. If you had an internal tear how are you feeling down there and how far pp are you?
