Should I get my ankle checked out?

In August I sprained my ankle but I self diagnosed that. It still hurts me. Not as bad as it did in August but it still hurts to walk sometimes and I can’t sit in certain positions and I can barely do squats. Jumping hurts badly. And every now and then there’s a little swelling. And sometimes it seems like I have to pop my ankle back it place for it to stop hurting.
