Inner labia growth and swelling

Hi I am only 17 years old and for past idk how many months I've been noticing that my inner labia is swollen or idk if it is like a lump or sm but it does not hurt or cause any discomfort and also the same side that is swollen also is bigger in length than the other side .Idk why this is happening and I am kinda scared to go to the doctor. Please help me.
