Still in pain 5 months pp

I don’t know who else to ask because this is extremely personal… does anyone else still have butthole pain 5 months pp? I literally cannot wean off miralax. Every time I only take half a cap instead of a full cap, I regret it the next morning. Pooping hurts so bad and my butthole continues to hurt most of the day. I had a 3rd degree tear so thinking this has something to do with it. Am I alone in this??
