I notices a nodule in the vaginal area. It is located between the external and internal labia on the left side. round, hard, pea-sized, not painful, no other symptoms. i have a gyne exam scheduled for tomorrow. Would like to find out more info about this prior to visit, but not sure what I m looking for. Please advise what I should be looking up for information prior to my visit. (I do have some medical knowledge based on my career in Clinical research) Thank you.
