What could this mean? whenever i insert a tampon, i experience a cramping and intense feeling of pressure type pain in my uterus/stomach area. it only occurs once the tampon is in but i am attempting to push it out of the applicator. it feels challenging

You : You could be dealing with vaginal polyps that are located in the introitus (entrance) of your vagina. This would cause pain or discomfort while inserting a tampon or penis, and would no longer cause discomfort once it has passed the polyps. The best thing for you to do is have a vaginal examination by your family doctor or gynecologist. Best of luck.
