I had dd2 7.5 months ago. I had a second degree tear but was right as rain after a week. Since Thursday my perineum has started to become tender. Today the scar feels raised and I have to sit and stand slowly. It is as sore as a few days post birth. Don't normally have any pelvic floor issues but wondered if i had done damage lifting hefty dd2 among other things or do I have an infection?
