Perineum pain at 5 months post partum ?

I’m 5 months post partum and I’ve noticed in the recent weeks that I’m having perineum pain (where you tear during birth) and then what seems like vaginal or uterine pain. I had a pretty severe tear when I delivered, but I thought I’d healed, but it is for whatever reason hurting again when I stretch or move my legs too far apart from each other. Tonight I went bowling and it seemed to kind of trigger the pain. The pain is kind of similar to the pain I felt when I had sex for the first time after giving birth. Is anybody experiencing something similar? I just feel like my vagina isn’t quite the same yet. Is this normal? Please someone tell me it’s not just me!
