While uterine fibroids are solid, non-cancerous muscle growths that don’t “pop” like cysts, they can undergo sudden changes that feel similar to a rupture. A true fibroids burst is rare, but fibroids can degenerate, a surface blood vessel can tear, or a fibroid may detach and cause intense, sudden pelvic pain. These events can lead to sharp pain, fever, bloating and even internal bleeding, all of which are medical emergencies. Visit USA Fibroid Centers for more information.
