Perineal feels sore & swollen

Hi mummies, this is my second pregnancy. I've just entered 24 weeks pregnant. For the past few weeks, I've noticed that my perineal area feels sore and swollen. Whenever I wanna past motion, it hurts and sometimes having trouble to push it out. Has any mummies encountered this and what remedies can help reduce the soreness and swollen? I've never had this during my first pregnancy. So this is new to me. );
