Should I go to the hospital if my body is hurting my ex was fighting me

My body is really sore and he threw me into the couch so my side is hurting since yesterday. And I’ll probably have some bruising in other areas since some parts I press on my body hurts along with the scrapes and scratches that I have. I don’t feel like going because of a long wait and it’s probably not an emergency since I can walk but I woke up and my body really hurts. I told him I don’t want to see him again and I want to keep my child away from him I really do it hurts me though because that’s her father. He said he’ll try to get her in court then but we have a domestic violence case that is closed. like this mf really fought me and tried to act like he didn’t hit me even though one other person saw!!
