Has anyone ever had a horrible anal fissure after delivery? I’ve been in pain since a few days after I left the hospital. I went for my check up with my doctor at 6 weeks and he didn’t even check me. Said I’ll be fine and do sitz baths. .. now it’s been almost 3 months and it still kills me. Any recommendations?
