TMI- hemmoriods and anal fissures- which doctor do I contact post pardom?

Hi all, I’m about 3 1/2 weeks post pardon and I struggled with hemmroids during pregnancy and now after they’ve gone away but I now think I have an anal fissure which is a million times worse. Which doctor should I call my OBGYN or my general practitioner? It’s been over a week and I have to see if there’s something I can do cause I’m dying😭😭
