Please give advice

Hello everyone please take time to read this. Maybe 4 days ago I woke up and the right side of my vagina lip farther down had a lot of pressure in it and it was swollen a little & sore. It almost felt like a tight muscle in your back or something. It definitely got better over a couple days but definitely still there? And this morning I woke up and my lymph nodes by my vagina are swollen. I wasn’t going to go to the gyno because I thought it was just like a tight muscle or something but anyone have any idea? I’m going to call if it doesn’t get better by the weekend. Never had this happen before
