My boyfriend beat me up last night

Our relationship hasn’t been that good lately (again) last night we got into an argument and he ended up beating me up worse than he has before.

My boyfriend and I both think I need medical help I’m still in a lot of pain and I called my doctor’s office and they can see me but I am scared and I don’t know what to say. he wants me to lie and say our toddler hit me in the face if they ask happened.

He’s sorry and feels bad and I don’t want my boyfriend to get in trouble because he’s a good person and I love him he just has problems but I feel bad lying especially blaming my toddler it sounds stupid. Will a doctor report this? Does a person need to be seen by a dr after getting “beat up”?

Edit: I’m not looking for relationship advice our relationship is very complex lots of ups and downs and I’m not perfect.
