Hello and welcome,
There is no need to be concerned.
From the description it is either a wart
or a cyst
of the vaginal wall. It would be difficult to say without examination. So please get an examination as already it is causing discomfort. If it is a cyst then it may increase in size and increase the discomfort further.
So just get an examination for the diagnosis. Treatment of both the conditions is simple.
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
