Yes, I feel that sort of heavy pressure in my vagina too. It’s mostly from pelvic floor spasms. Pelvic floor physical therapy, acupuncture and compounded suppositories of Flexeril (muscle relaxant) and Lidocaine (numbing agent) help me a lot. But make sure nothing else is happening, like pelvic organ prolapse. But as I recall, you’re probably too young for that yes?
