Ripped hymen three years after lost virginity?

I have been having sex for three years, and have never had something like this happen. About a week ago it really hurt while I was having sex, and it still hasn't gone away. i have still been having sex since once a day and have also gone a day or two without sex, sometimes i can barely feel it and other times I have to stop because it hurts so much. I've done some research, and look at the area and it seems like I have just ripped my hymen but I figured that had already happened since i lost my virginity so long ago and I also ride horses. I'm just worried it might be something else because it feels like the ripped part of the skin is getting harder, but maybe it's just scar tissue?
