Help.. 😫😰

When I gave birth 9 months ago I had an internal 3rd degree tear. I woke up this morning and it is hurting so bad. It literally feels like a fresh tear again like when I first gave birth. I’m having to walk around slowly and sit carefully all over again because it feels like I’ve just given birth again. This can’t be normal 9 months pp right? It hasn’t happened up until now.. Is it possible that it has split back open? Is there anything I can do? I feel like if I go to the ER they will say they can’t do anything? 😰
